/* These are defined by the user (or the compiler)
to specify the desired environment:
__STRICT_ANSI__ ISO Standard C.

_ISOC11_SOURCE Extensions to ISO C99 from ISO C11.
_ISOC2X_SOURCE Extensions to ISO C99 from ISO C2X.

Extensions to ISO C11 from TS 18661-3:2015.
__STDC_WANT_IEC_60559_EXT__
ISO C2X interfaces defined only in Annex F.
_POSIX_SOURCE IEEE Std 1003.1.
_POSIX_C_SOURCE If ==1, like _POSIX_SOURCE; if >=2 add IEEE Std 1003.2;
if >=199309L, add IEEE Std 1003.1b-1993;
if >=199506L, add IEEE Std 1003.1c-1995;
if >=200112L, all of IEEE 1003.1-2004
if >=200809L, all of IEEE 1003.1-2008
_XOPEN_SOURCE Includes POSIX and XPG things. Set to 500 if
Single Unix conformance is wanted, to 600 for the
sixth revision, to 700 for the seventh revision.
_XOPEN_SOURCE_EXTENDED XPG things and X/Open Unix extensions.
_LARGEFILE_SOURCE Some more functions for correct standard I/O.
_LARGEFILE64_SOURCE Additional functionality from LFS for large files.
_FILE_OFFSET_BITS=N Select default filesystem interface.
_ATFILE_SOURCE Additional *at interfaces.
_DYNAMIC_STACK_SIZE_SOURCE Select correct (but non compile-time constant)
MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
_GNU_SOURCE All of the above, plus GNU extensions.
_DEFAULT_SOURCE The default set of features (taking precedence over
__STRICT_ANSI__).
_FORTIFY_SOURCE Add security hardening to many library functions.
Set to 1, 2 or 3; 3 performs stricter checks than 2, which
performs stricter checks than 1.
_REENTRANT, _THREAD_SAFE
Obsolete; equivalent to _POSIX_C_SOURCE=199506L.
The `-ansi' switch to the GNU C compiler, and standards conformance
options such as `-std=c99', define __STRICT_ANSI__. If none of
these are defined, or if _DEFAULT_SOURCE is defined, the default is
to have _POSIX_SOURCE set to one and _POSIX_C_SOURCE set to
200809L, as well as enabling miscellaneous functions from BSD and
SVID. If more than one of these are defined, they accumulate. For
example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE together
give you ISO C, 1003.1, and 1003.2, but nothing else.
These are defined by this file and are used by the
header files to decide what to declare or define:
__GLIBC_USE (F) Define things from feature set F. This is defined
to 1 or 0; the subsequent macros are either defined
or undefined, and those tests should be moved to
__GLIBC_USE.
__USE_ISOC11 Define ISO C11 things.
__USE_ISOC99 Define ISO C99 things.
__USE_ISOC95 Define ISO C90 AMD1 (C95) things.
__USE_ISOCXX11 Define ISO C++11 things.
__USE_POSIX Define IEEE Std 1003.1 things.
__USE_POSIX2 Define IEEE Std 1003.2 things.
__USE_POSIX199309 Define IEEE Std 1003.1, and .1b things.
__USE_POSIX199506 Define IEEE Std 1003.1, .1b, .1c and .1i things.
__USE_XOPEN Define XPG things.
__USE_XOPEN_EXTENDED Define X/Open Unix things.
__USE_UNIX98 Define Single Unix V2 things.
__USE_XOPEN2K Define XPG6 things.
__USE_XOPEN2KXSI Define XPG6 XSI things.
__USE_XOPEN2K8 Define XPG7 things.
__USE_XOPEN2K8XSI Define XPG7 XSI things.
__USE_LARGEFILE Define correct standard I/O things.
__USE_LARGEFILE64 Define LFS things with separate names.
__USE_FILE_OFFSET64 Define 64bit interface as default.
__USE_MISC Define things from 4.3BSD or System V Unix.
__USE_ATFILE Define *at interfaces and AT_* constants for them.
__USE_DYNAMIC_STACK_SIZE Define correct (but non compile-time constant)
MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
__USE_GNU Define GNU extensions.
__USE_FORTIFY_LEVEL Additional security measures used, according to level.
The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
defined by this file unconditionally. `__GNU_LIBRARY__' is provided
only for compatibility. All new code should use the other symbols
to test for features.
All macros listed above as possibly being defined by this file are
explicitly undefined if they are not explicitly defined.
Feature-test macros that are not defined by the user or compiler
but are implied by the other feature-test macros defined (or by the
lack of any definitions) are defined by the file.
ISO C feature test macros depend on the definition of the macro
when an affected header is included, not when the first system
header is included, and so they are handled in
<bits/libc-header-start.h>, which does not have a multiple include
guard. Feature test macros that can be handled from the first
system header included are handled here. */

macros for each of the OS types we define below. The definitions
of those macros must use the following macros for underlying types.
We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
variants of each of the following integer types on this machine.
16 -- "natural" 16-bit type (always short)
32 -- "natural" 32-bit type (always int)
64 -- "natural" 64-bit type (long or long long)
LONG32 -- 32-bit type, traditionally long
QUAD -- 64-bit type, traditionally long long
WORD -- natural type of __WORDSIZE bits (int or long)
LONGWORD -- type of __WORDSIZE bits, traditionally long
We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
conventional uses of `long' or `long long' type modifiers match the
types we define, even when a less-adorned type would be the same size.
This matters for (somewhat) portably writing printf/scanf formats for
these types, where using the appropriate l or ll format modifiers can
make the typedefs and the formats match up across all GNU platforms. If
we used `long' when it's 64 bits where `long long' is expected, then the
compiler would warn about the formats not matching the argument types,
and the programmer changing them to shut up the compiler would break the
program's portability.
Here we assume what is presently the case in all the GCC configurations
we support: long long is always 64 bits, long is always word/address size,
and int is always 32 bits. */

missing arguments, 'optopt' is set to the option letter, and '?' is
returned.
The OPTS string is a list of characters which are recognized option
letters, optionally followed by colons, specifying that that letter
takes an argument, to be placed in 'optarg'.
If a letter in OPTS is followed by two colons, its argument is
optional. This behavior is specific to the GNU 'getopt'.
The argument '--' causes premature termination of argument
scanning, explicitly telling 'getopt' that there are no more
options.
If OPTS begins with '-', then non-option arguments are treated as
arguments to the option '\1'. This behavior is specific to the GNU
'getopt'. If OPTS begins with '+', or POSIXLY_CORRECT is set in
the environment, then do not permute arguments.
For standards compliance, the 'argv' argument has the type
char *const *, but this is inaccurate; if argument permutation is
enabled, the argv array (not the strings it points to) must be

/*
The 'zlib' compression library provides in-memory compression and
decompression functions, including integrity checks of the uncompressed data.
This version of the library supports only one compression method (deflation)
but other algorithms will be added later and will have the same stream
interface.
Compression can be done in a single step if the buffers are large enough,
or can be done by repeated calls of the compression function. In the latter
case, the application must provide more input and/or consume the output
(providing more output space) before each call.
The compressed data format used by default by the in-memory functions is
the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
around a deflate stream, which is itself documented in RFC 1951.
The library also supports reading and writing files in gzip (.gz) format
with an interface similar to that of stdio using the functions that start
with "gz". The gzip format is different from the zlib format. gzip is a
gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
This library can optionally read and write gzip and raw deflate streams in
memory as well.
The zlib format was designed to be compact and fast for use in memory
and on communications channels. The gzip format was designed for single-
file compression on file systems, has a larger header than zlib to maintain
directory information, and uses a different, slower check method than zlib.
The library does not install any signal handler. The decoder checks
the consistency of the compressed data, so the library should never crash
even in the case of corrupted input.

The application must update next_in and avail_in when avail_in has dropped
to zero. It must update next_out and avail_out when avail_out has dropped
to zero. The application must initialize zalloc, zfree and opaque before
calling the init function. All other fields are set by the compression
library and must not be updated by the application.
The opaque value provided by the application will be passed as the first
parameter for calls of zalloc and zfree. This can be useful for custom
memory management. The compression library attaches no meaning to the
opaque value.
zalloc must return Z_NULL if there is not enough memory for the object.
If zlib is used in a multi-threaded application, zalloc and zfree must be
thread safe. In that case, zlib is thread-safe. When zalloc and zfree are
Z_NULL on entry to the initialization function, they are set to internal
routines that use the standard library functions malloc() and free().
On 16-bit systems, the functions zalloc and zfree must be able to allocate
exactly 65536 bytes, but will not be required to allocate more than this if
the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS, pointers
returned by zalloc for objects of exactly 65536 bytes *must* have their
offset normalized to zero. The default allocation function provided by this
library ensures this (see zutil.c). To reduce memory requirements and avoid
any allocation of 64K objects, at the expense of compression ratio, compile
the library with -DMAX_WBITS=14 (see zconf.h).
The fields total_in and total_out can be used for statistics or progress
reports. After compression, total_in holds the total size of the
uncompressed data and may be saved for use by the decompressor (particularly
if the decompressor wants to decompress everything in a single step).

ZEXTERN int ZEXPORT deflateInit OF((z_streamp strm, int level));
Initializes the internal stream state for compression. The fields
zalloc, zfree and opaque must be initialized before by the caller. If
zalloc and zfree are set to Z_NULL, deflateInit updates them to use default
allocation functions.
The compression level must be Z_DEFAULT_COMPRESSION, or between 0 and 9:
1 gives best speed, 9 gives best compression, 0 gives no compression at all
(the input data is simply copied a block at a time). Z_DEFAULT_COMPRESSION
requests a default compromise between speed and compression (currently
equivalent to level 6).
deflateInit returns Z_OK if success, Z_MEM_ERROR if there was not enough
memory, Z_STREAM_ERROR if level is not a valid compression level, or
Z_VERSION_ERROR if the zlib library version (zlib_version) is incompatible
with the version assumed by the caller (ZLIB_VERSION). msg is set to null
if there is no error message. deflateInit does not perform any compression:
this will be done by deflate().

deflate compresses as much data as possible, and stops when the input
buffer becomes empty or the output buffer becomes full. It may introduce
some output latency (reading input without producing any output) except when
forced to flush.
The detailed semantics are as follows. deflate performs one or both of the
following actions:
- Compress more input starting at next_in and update next_in and avail_in
accordingly. If not all input can be processed (because there is not
enough room in the output buffer), next_in and avail_in are updated and
processing will resume at this point for the next call of deflate().
- Generate more output starting at next_out and update next_out and avail_out
accordingly. This action is forced if the parameter flush is non zero.
Forcing flush frequently degrades the compression ratio, so this parameter
should be set only when necessary. Some output may be provided even if
flush is zero.
Before the call of deflate(), the application should ensure that at least
one of the actions is possible, by providing more input and/or consuming more
output, and updating avail_in or avail_out accordingly; avail_out should
never be zero before the call. The application can consume the compressed
output when it wants, for example when the output buffer is full (avail_out
== 0), or after each call of deflate(). If deflate returns Z_OK and with
zero avail_out, it must be called again after making room in the output
buffer because there might be more output pending. See deflatePending(),
which can be used if desired to determine whether or not there is more output
in that case.
Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
decide how much data to accumulate before producing output, in order to
maximize compression.
If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
flushed to the output buffer and the output is aligned on a byte boundary, so
that the decompressor can get all input data available so far. (In
particular avail_in is zero after the call if enough output space has been
provided before the call.) Flushing may degrade compression for some
compression algorithms and so it should be used only when necessary. This
completes the current deflate block and follows it with an empty stored block
that is three bits plus filler bits to the next byte, followed by four bytes
(00 00 ff ff).
If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
output buffer, but the output is not aligned to a byte boundary. All of the
input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
This completes the current deflate block and follows it with an empty fixed
codes block that is 10 bits long. This assures that enough bytes are output
in order for the decompressor to finish the block before the empty fixed
codes block.
If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
seven bits of the current block are held to be written as the next byte after
the next deflate block is completed. In this case, the decompressor may not
be provided enough bits at this point in order to complete decompression of
the data provided so far to the compressor. It may need to wait for the next
block to be emitted. This is for advanced applications that need to control
the emission of deflate blocks.
If flush is set to Z_FULL_FLUSH, all output is flushed as with
Z_SYNC_FLUSH, and the compression state is reset so that decompression can
restart from this point if previous compressed data has been damaged or if
random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
compression.
If deflate returns with avail_out == 0, this function must be called again
with the same value of the flush parameter and more output space (updated
avail_out), until the flush is complete (deflate returns with non-zero
avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
avail_out is greater than six to avoid repeated flush markers due to
avail_out == 0 on return.
If the parameter flush is set to Z_FINISH, pending input is processed,
pending output is flushed and deflate returns with Z_STREAM_END if there was
enough output space. If deflate returns with Z_OK or Z_BUF_ERROR, this
function must be called again with Z_FINISH and more output space (updated
avail_out) but no more input data, until it returns with Z_STREAM_END or an
error. After deflate has returned Z_STREAM_END, the only possible operations
on the stream are deflateReset or deflateEnd.
Z_FINISH can be used in the first deflate call after deflateInit if all the
compression is to be done in a single step. In order to complete in one
call, avail_out must be at least the value returned by deflateBound (see
below). Then deflate is guaranteed to return Z_STREAM_END. If not enough
output space is provided, deflate will not return Z_STREAM_END, and it must
be called again as described above.
deflate() sets strm->adler to the Adler-32 checksum of all input read
so far (that is, total_in bytes). If a gzip stream is being generated, then
strm->adler will be the CRC-32 checksum of the input read so far. (See
deflateInit2 below.)
deflate() may update strm->data_type if it can make a good guess about
the input data type (Z_BINARY or Z_TEXT). If in doubt, the data is
considered binary. This field is only for information purposes and does not
affect the compression algorithm in any manner.
deflate() returns Z_OK if some progress has been made (more input
processed or more output produced), Z_STREAM_END if all input has been
consumed and all output has been produced (only when flush is set to
Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
if next_in or next_out was Z_NULL or the state was inadvertently written over
by the application), or Z_BUF_ERROR if no progress is possible (for example
avail_in or avail_out was zero). Note that Z_BUF_ERROR is not fatal, and
deflate() can be called again with more input and more output space to
continue compressing.

that is deferred until inflate() is called.
*/
extern int inflate (z_streamp strm, int flush);
/*
inflate decompresses as much data as possible, and stops when the input
buffer becomes empty or the output buffer becomes full. It may introduce
some output latency (reading input without producing any output) except when
forced to flush.
The detailed semantics are as follows. inflate performs one or both of the
following actions:
- Decompress more input starting at next_in and update next_in and avail_in
accordingly. If not all input can be processed (because there is not
enough room in the output buffer), then next_in and avail_in are updated
accordingly, and processing will resume at this point for the next call of
inflate().
- Generate more output starting at next_out and update next_out and avail_out
accordingly. inflate() provides as much output as possible, until there is
no more input data or no more space in the output buffer (see below about
the flush parameter).
Before the call of inflate(), the application should ensure that at least
one of the actions is possible, by providing more input and/or consuming more
output, and updating the next_* and avail_* values accordingly. If the
caller of inflate() does not provide both available input and available
output space, it is possible that there will be no progress made. The
application can consume the uncompressed output when it wants, for example
when the output buffer is full (avail_out == 0), or after each call of
inflate(). If inflate returns Z_OK and with zero avail_out, it must be
called again after making room in the output buffer because there might be
more output pending.
The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much
output as possible to the output buffer. Z_BLOCK requests that inflate()
stop if and when it gets to the next deflate block boundary. When decoding
the zlib or gzip format, this will cause inflate() to return immediately
after the header and before the first block. When doing a raw inflate,
inflate() will go ahead and process the first block, and will return when it
gets to the end of that block, or when it runs out of data.
The Z_BLOCK option assists in appending to or combining deflate streams.
To assist in this, on return inflate() always sets strm->data_type to the
number of unused bits in the last byte taken from strm->next_in, plus 64 if
inflate() is currently decoding the last block in the deflate stream, plus
128 if inflate() returned immediately after decoding an end-of-block code or
decoding the complete header up to just before the first byte of the deflate
stream. The end-of-block will not be indicated until all of the uncompressed
data from that block has been written to strm->next_out. The number of
unused bits may in general be greater than seven, except when bit 7 of
data_type is set, in which case the number of unused bits will be less than
eight. data_type is set as noted here every time inflate() returns for all
flush options, and so can be used to determine the amount of currently
consumed input in bits.
The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
end of each deflate block header is reached, before any actual data in that
block is decoded. This allows the caller to determine the length of the
deflate block header for later use in random access within a deflate block.
256 is added to the value of strm->data_type when inflate() returns
immediately after reaching the end of the deflate block header.
inflate() should normally be called until it returns Z_STREAM_END or an
error. However if all decompression is to be performed in a single step (a
single call of inflate), the parameter flush should be set to Z_FINISH. In
this case all pending input is processed and all pending output is flushed;
avail_out must be large enough to hold all of the uncompressed data for the
operation to complete. (The size of the uncompressed data may have been
saved by the compressor for this purpose.) The use of Z_FINISH is not
required to perform an inflation in one step. However it may be used to
inform inflate that a faster approach can be used for the single inflate()
call. Z_FINISH also informs inflate to not maintain a sliding window if the
stream completes, which reduces inflate's memory footprint. If the stream
does not complete, either because not all of the stream is provided or not
enough output space is provided, then a sliding window will be allocated and
inflate() can be called again to continue the operation as if Z_NO_FLUSH had
been used.
In this implementation, inflate() always flushes as much output as
possible to the output buffer, and always uses the faster approach on the
first call. So the effects of the flush parameter in this implementation are
on the return value of inflate() as noted below, when inflate() returns early
when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
memory for a sliding window when Z_FINISH is used.
If a preset dictionary is needed after this call (see inflateSetDictionary
below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
strm->adler to the Adler-32 checksum of all output produced so far (that is,
total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
below. At the end of the stream, inflate() checks that its computed Adler-32
checksum is equal to that saved by the compressor and returns Z_STREAM_END
only if the checksum is correct.
inflate() can decompress and check either zlib-wrapped or gzip-wrapped
deflate data. The header type is detected automatically, if requested when
initializing with inflateInit2(). Any information contained in the gzip
header is not retained unless inflateGetHeader() is used. When processing
gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
produced so far. The CRC-32 is checked against the gzip trailer, as is the
uncompressed length, modulo 2^32.
inflate() returns Z_OK if some progress has been made (more input processed
or more output produced), Z_STREAM_END if the end of the compressed data has
been reached and all uncompressed output has been produced, Z_NEED_DICT if a
preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
corrupted (input stream not conforming to the zlib format or incorrect check
value, in which case strm->msg points to a string with a more specific
error), Z_STREAM_ERROR if the stream structure was inconsistent (for example
next_in or next_out was Z_NULL, or the state was inadvertently written over
by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR
if no progress was possible or if there was not enough room in the output
buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
inflate() can be called again with more input and more output space to
continue decompressing. If Z_DATA_ERROR is returned, the application may
then call inflateSync() to look for a good compression block if a partial
recovery of the data is to be attempted.

/*
ZEXTERN int ZEXPORT deflateInit2 OF((z_streamp strm,
int level,
int method,
int windowBits,
int memLevel,
int strategy));
This is another version of deflateInit with more compression options. The
fields zalloc, zfree and opaque must be initialized before by the caller.
The method parameter is the compression method. It must be Z_DEFLATED in
this version of the library.
The windowBits parameter is the base two logarithm of the window size
(the size of the history buffer). It should be in the range 8..15 for this
version of the library. Larger values of this parameter result in better
compression at the expense of memory usage. The default value is 15 if
deflateInit is used instead.
For the current implementation of deflate(), a windowBits value of 8 (a
window size of 256 bytes) is not supported. As a result, a request for 8
will result in 9 (a 512-byte window). In that case, providing 8 to
inflateInit2() will result in an error when the zlib header with 9 is
checked against the initialization of inflate(). The remedy is to not use 8
with deflateInit2() with this initialization, or at least in that case use 9
with inflateInit2().
windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
determines the window size. deflate() will then generate raw deflate data
with no zlib header or trailer, and will not compute a check value.
windowBits can also be greater than 15 for optional gzip encoding. Add
16 to windowBits to write a simple gzip header and trailer around the
compressed data instead of a zlib wrapper. The gzip header will have no
file name, no extra data, no comment, no modification time (set to zero), no
header crc, and the operating system will be set to the appropriate value,
if the operating system was determined at compile time. If a gzip stream is
being written, strm->adler is a CRC-32 instead of an Adler-32.
For raw deflate or gzip encoding, a request for a 256-byte window is
rejected as invalid, since only the zlib header provides a means of
transmitting the window size to the decompressor.
The memLevel parameter specifies how much memory should be allocated
for the internal compression state. memLevel=1 uses minimum memory but is
slow and reduces compression ratio; memLevel=9 uses maximum memory for
optimal speed. The default value is 8. See zconf.h for total memory usage
as a function of windowBits and memLevel.
The strategy parameter is used to tune the compression algorithm. Use the
value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
string match), or Z_RLE to limit match distances to one (run-length
encoding). Filtered data consists mostly of small values with a somewhat
random distribution. In this case, the compression algorithm is tuned to
compress them better. The effect of Z_FILTERED is to force more Huffman
coding and less string matching; it is somewhat intermediate between
Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as
fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The
strategy parameter only affects the compression ratio but not the
correctness of the compressed output even if it is not set appropriately.
Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
decoder for special applications.
deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
incompatible with the version assumed by the caller (ZLIB_VERSION). msg is
set to null if there is no error message. deflateInit2 does not perform any
compression: this will be done by deflate().
*/
extern int deflateSetDictionary (z_streamp strm, const Bytef *dictionary, uInt dictLength)
;
/*
Initializes the compression dictionary from the given byte sequence
without producing any compressed output. When using the zlib format, this
function must be called immediately after deflateInit, deflateInit2 or
deflateReset, and before any call of deflate. When doing raw deflate, this
function must be called either before any call of deflate, or immediately
after the completion of a deflate block, i.e. after all input has been
consumed and all output has been delivered when using any of the flush
options Z_BLOCK, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, or Z_FULL_FLUSH. The
compressor and decompressor must use exactly the same dictionary (see
inflateSetDictionary).
The dictionary should consist of strings (byte sequences) that are likely
to be encountered later in the data to be compressed, with the most commonly
used strings preferably put towards the end of the dictionary. Using a
dictionary is most useful when the data to be compressed is short and can be
predicted with good accuracy; the data can then be compressed better than
with the default empty dictionary.
Depending on the size of the compression data structures selected by
deflateInit or deflateInit2, a part of the dictionary may in effect be
discarded, for example if the dictionary is larger than the window size
provided in deflateInit or deflateInit2. Thus the strings most likely to be
useful should be put at the end of the dictionary, not at the front. In
addition, the current implementation of deflate will use at most the window
size minus 262 bytes of the provided dictionary.
Upon return of this function, strm->adler is set to the Adler-32 value
of the dictionary; the decompressor may later use this value to determine
which dictionary has been used by the compressor. (The Adler-32 value
applies to the whole dictionary even if only a subset of the dictionary is
actually used by the compressor.) If a raw deflate was requested, then the
Adler-32 value is not computed and strm->adler is not set.
deflateSetDictionary returns Z_OK if success, or Z_STREAM_ERROR if a
parameter is invalid (e.g. dictionary being Z_NULL) or the stream state is
inconsistent (for example if deflate has already been called for this stream
or if not at a block boundary for raw deflate). deflateSetDictionary does

Z_NULL, then only the dictionary length is returned, and nothing is copied.
Similarly, if dictLength is Z_NULL, then it is not set.
deflateGetDictionary() may return a length less than the window size, even
when more than the window size in input has been provided. It may return up
to 258 bytes less in that case, due to how zlib's implementation of deflate
manages the sliding window and lookahead for matches, where matches can be
up to 258 bytes long. If the application needs the last window-size bytes of

to switch to a different kind of input data requiring a different strategy.
If the compression approach (which is a function of the level) or the
strategy is changed, and if there have been any deflate() calls since the
state was initialized or reset, then the input available so far is
compressed with the old level and strategy using deflate(strm, Z_BLOCK).
There are three approaches for the compression levels 0, 1..3, and 4..9
respectively. The new level and strategy will take effect at the next call
of deflate().
If a deflate(strm, Z_BLOCK) is performed by deflateParams(), and it does
not have enough output space to complete, then the parameter change will not
take effect. In this case, deflateParams() can be called again with the
same parameters and more output space to try again.
In order to assure a change in the parameters on the first try, the
deflate stream should be flushed using deflate() with Z_BLOCK or other flush

Then no more input data should be provided before the deflateParams() call.

there was not enough output space to complete the compression of the

ZEXTERN int ZEXPORT inflateInit2 OF((z_streamp strm,
int windowBits));
This is another version of inflateInit with an extra parameter. The
fields next_in, avail_in, zalloc, zfree and opaque must be initialized
before by the caller.
The windowBits parameter is the base two logarithm of the maximum window
size (the size of the history buffer). It should be in the range 8..15 for
this version of the library. The default value is 15 if inflateInit is used
instead. windowBits must be greater than or equal to the windowBits value
provided to deflateInit2() while compressing, or it must be equal to 15 if
deflateInit2() was not used. If a compressed stream with a larger window
size is given as input, inflate() will return with the error code
Z_DATA_ERROR instead of trying to allocate a larger window.
windowBits can also be zero to request that inflate use the window size in
the zlib header of the compressed stream.
windowBits can also be -8..-15 for raw inflate. In this case, -windowBits
determines the window size. inflate() will then process raw deflate data,
not looking for a zlib or gzip header, not generating a check value, and not
looking for any check values for comparison at the end of the stream. This
is for use with other formats that use the deflate compressed data format
such as zip. Those formats provide their own check values. If a custom
format is developed using the raw deflate format for compressed data, it is
recommended that a check value such as an Adler-32 or a CRC-32 be applied to
the uncompressed data as is done in the zlib, gzip, and zip formats. For
most applications, the zlib format should be used as is. Note that comments
above on the use in deflateInit2() applies to the magnitude of windowBits.
windowBits can also be greater than 15 for optional gzip decoding. Add
32 to windowBits to enable zlib and gzip decoding with automatic header
detection, or add 16 to decode only the gzip format (the zlib format will
return a Z_DATA_ERROR). If a gzip stream is being decoded, strm->adler is a
CRC-32 instead of an Adler-32. Unlike the gunzip utility and gzread() (see
below), inflate() will *not* automatically decode concatenated gzip members.
inflate() will return Z_STREAM_END at the end of the gzip member. The state
would need to be reset to continue decoding a subsequent gzip member. This
*must* be done if there is more data after a gzip member, in order for the
decompression to be compliant with the gzip standard (RFC 1952).

it is the number of bits back from the current bit position in the input of

is completed, at which time head->done is set to one. If a zlib stream is
being decoded, then head->done is set to -1 to indicate that there will be
no gzip header information forthcoming. Note that Z_BLOCK or Z_TREES can be
used to force inflate() to return immediately after header processing is
complete and before any actual data is decompressed.
The text, time, xflags, and os fields are filled in with the gzip header
contents. hcrc is set to true if there is a header CRC. (The header CRC
was valid if done is set to one.) If extra is not Z_NULL, then extra_max
contains the maximum number of bytes to write to extra. Once done is true,
extra_len contains the actual extra field length, and extra contains the
extra field, or that field truncated if extra_max is less than extra_len.
If name is not Z_NULL, then up to name_max characters are written there,
terminated with a zero unless the length is greater than name_max. If
comment is not Z_NULL, then up to comm_max characters are written there,
terminated with a zero unless the length is greater than comm_max. When any
of extra, name, or comment are not Z_NULL and the respective field is not

allocated memory, then the application will need to save those pointers
elsewhere so that they can be eventually freed.
If inflateGetHeader is not used, then the header information is simply
discarded. The header is always checked for validity, including the header
CRC if present. inflateReset() will reset the process to discard the header

/*
inflateBack() does a raw inflate with a single call using a call-back
interface for input and output. This is potentially more efficient than
inflate() for file i/o applications, in that it avoids copying between the
output and the sliding window by simply making the window itself the output
buffer. inflate() can be faster on modern CPUs when used with large
buffers. inflateBack() trusts the application to not change the output
buffer passed by the output function, at least until inflateBack() returns.
inflateBackInit() must be called first to allocate the internal state
and to initialize the state with the user-provided window buffer.
inflateBack() may then be used multiple times to inflate a complete, raw
deflate stream with each call. inflateBackEnd() is then called to free the
allocated state.
A raw deflate stream is one with no zlib or gzip header or trailer.
This routine would normally be used in a utility that reads zip or gzip
files and writes out uncompressed files. The utility would decode the
header and process the trailer on its own, hence this routine expects only
the raw deflate stream to decompress. This is different from the default
behavior of inflate(), which expects a zlib header and trailer around the
deflate stream.
inflateBack() uses two subroutines supplied by the caller that are then
called by inflateBack() for input and output. inflateBack() calls those
routines until it reads a complete deflate stream and writes out all of the
uncompressed data, or until it encounters an error. The function's
parameters and return types are defined above in the in_func and out_func
typedefs. inflateBack() will call in(in_desc, &buf) which should return the
number of bytes of provided input, and a pointer to that input in buf. If
there is no input available, in() must return zero -- buf is ignored in that
case -- and inflateBack() will return a buffer error. inflateBack() will
call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].
out() should return zero on success, or non-zero on failure. If out()
returns non-zero, inflateBack() will return with an error. Neither in() nor
out() are permitted to change the contents of the window provided to
inflateBackInit(), which is also the buffer that out() uses to write from.
The length written by out() will be at most the window size. Any non-zero
amount of input may be provided by in().
For convenience, inflateBack() can be provided input on the first call by
setting strm->next_in and strm->avail_in. If that input is exhausted, then
in() will be called. Therefore strm->next_in must be initialized before
calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
must also be initialized, and then if strm->avail_in is not zero, input will
initially be taken from strm->next_in[0 .. strm->avail_in - 1].
The in_desc and out_desc parameters of inflateBack() is passed as the
first parameter of in() and out() respectively when they are called. These
descriptors can be optionally used to pass any information that the caller-
supplied in() and out() functions need to do their job.
On return, inflateBack() will set strm->next_in and strm->avail_in to
pass back any unused input that was provided by the last in() call. The
return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
if in() or out() returned an error, Z_DATA_ERROR if there was a format error
in the deflate stream (in which case strm->msg is set to indicate the nature
of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
In the case of Z_BUF_ERROR, an input or output error can be distinguished
using strm->next_in which will be Z_NULL only if in() returned an error. If
strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
non-zero. (in() will always be called before out(), so strm->next_in is
assured to be defined if out() returns non-zero.) Note that inflateBack()
cannot return Z_OK.

Open the gzip (.gz) file at path for reading and decompressing, or
compressing and writing. The mode parameter is as in fopen ("rb" or "wb")
but can also include a compression level ("wb9") or a strategy: 'f' for
filtered data as in "wb6f", 'h' for Huffman-only compression as in "wb1h",
'R' for run-length encoding as in "wb1R", or 'F' for fixed code compression
as in "wb9F". (See the description of deflateInit2 for more information
about the strategy parameter.) 'T' will request transparent writing or
appending with no compression and not using the gzip format.
"a" can be used instead of "w" to request that the gzip stream that will
be written be appended to the file. "+" will result in an error, since
reading and writing to the same gzip file is not supported. The addition of
"x" when writing will create the file exclusively, which fails if the file
already exists. On systems that support it, the addition of "e" when
reading or writing will set the flag to close the file on an execve() call.
These functions, as well as gzip, will read and decode a sequence of gzip
streams in a file. The append function of gzopen() can be used to create
such a file. (Also see gzflush() for another way to do this.) When
appending, gzopen does not test whether the file begins with a gzip stream,
nor does it look for the end of the gzip streams to begin appending. gzopen
will simply append a gzip stream to the existing file.
gzopen can be used to read a file which is not in gzip format; in this
case gzread will directly read from the file without decompression. When
reading, this will be detected automatically by looking for the magic two-
byte gzip header.
gzopen returns NULL if the file could not be opened, if there was
insufficient memory to allocate the gzFile state, or if an invalid mode was

descriptor fd, just like fclose(fdopen(fd, mode)) closes the file descriptor

gzdopen does not close fd if it fails. If you are using fileno() to get the

Read and decompress one byte from file. gzgetc returns this byte or -1
in case of end of file or error. This is implemented as a macro for speed.

it does not check to see if file is NULL, nor whether the structure file
points to has been clobbered or not.

Push c back onto the stream for file to be read as the first character on
the next read. At least one character of push-back is always allowed.

fail if c is -1, and may fail if a character has been pushed but not read
yet. If gzungetc is used immediately after gzopen or gzdopen, at least the
output buffer size of pushed characters is allowed. (See gzbuffer above.)
The pushed character will be discarded if the stream is repositioned with

Flush all pending output to file. The parameter flush is as in the
deflate() function. The return value is the zlib error number (see function
gzerror below). gzflush is only permitted when writing.
If the flush parameter is Z_FINISH, the remaining data is written and the
gzip stream is completed in the output. If gzwrite() is called again, a new
gzip stream will be started in the output. gzread() is able to read such
concatenated gzip streams.
gzflush should be called only when strictly necessary because it will
degrade compression if called too often.

Set the starting position to offset relative to whence for the next gzread

uncompressed data stream. The whence parameter is defined as in lseek(2);
the value SEEK_END is not supported.
If the file is opened for reading, this function is emulated but can be
extremely slow. If the file is opened for writing, only forward seeks are
supported; gzseek then compresses a sequence of zeroes up to the new
starting position.
gzseek returns the resulting offset location as measured in bytes from
the beginning of the uncompressed stream, or -1 in case of error, in
particular if the file is opened for writing and the new starting position
would be before the current position.

the middle of a file using gzdopen().
gztell(file) is equivalent to gzseek(file, 0L, SEEK_CUR)

ZEXTERN z_off_t ZEXPORT gzoffset OF((gzFile file));
Return the current compressed (actual) read or write offset of file. This
offset includes the count of bytes that precede the gzip stream, for example
when appending or when using gzdopen() for reading. When reading, the
offset does not include as yet unused buffered input. This information can
be used for a progress indicator. On error, gzoffset() returns -1.

/*
Return true (1) if the end-of-file indicator for file has been set while
reading, false (0) otherwise. Note that the end-of-file indicator is set
only if the read tried to go past the end of the input, but came up short.
Therefore, just like feof(), gzeof() may return false even if there is no
more data to read, in the event that the last read request was for the exact
number of bytes remaining in the input file. This will happen if the input
file size is an exact multiple of the buffer size.
If gzeof() returns true, then the read functions will return no more data,
unless the end-of-file indicator is reset by gzclearerr() and the input file
has grown since the previous end of file was detected.

/*
Return true (1) if file is being copied directly while reading, or false
(0) if file is a gzip stream being decompressed.
If the input file is empty, gzdirect() will return true, since the input
does not contain a gzip stream.
If gzdirect() is used immediately after gzopen() or gzdopen() it will
cause buffers to be allocated to allow reading the file to determine if it
is a gzip file. Therefore if gzbuffer() is used, it should be called before
gzdirect().
When writing, gzdirect() returns true (1) if transparent writing was
requested ("wT" for the gzopen() mode), or false (0) otherwise. (Note:
gzdirect() is not needed when writing. Transparent writing must be
explicitly requested, so the application already knows the answer. When
linking statically, using gzdirect() will include all of the zlib code for
gzip file reading and decompression, which may not be desired.)

/*
Flush all pending output for file, if necessary, close file and
deallocate the (de)compression state. Note that once file is closed, you
cannot call gzerror with file, since its structures have been deallocated.
gzclose must not be called more than once on the same file, just as free
must not be called more than once on the same allocation.
gzclose will return Z_STREAM_ERROR if file is not valid, Z_ERRNO on a
file operation error, Z_MEM_ERROR if out of memory, Z_BUF_ERROR if the
last read ended in the middle of a gzip stream, or Z_OK on success.

Same as gzclose(), but gzclose_r() is only for use when reading, and
gzclose_w() is only for use when writing or appending. The advantage to
using these instead of gzclose() is that they avoid linking in zlib
compression or decompression code that is not used when only reading or only
writing respectively. If gzclose() is used, then both compression and
decompression code will be included the application when linking to a static
zlib library.
*/

Return the error message for the last error which occurred on file.
errnum is set to zlib error number. If an error occurred in the file system
and not in the compression library, errnum is set to Z_ERRNO and the
application may consult errno to get the exact error code.
The application must not modify the returned string. Future calls to
this function may invalidate the previously returned string. If file is
closed, then the string previously returned by gzerror will no longer be
available.
gzerror() should be used to distinguish errors from end-of-file for those
functions above that do not distinguish those cases in their return values.

If buf is Z_NULL, this function returns the required initial value for the
crc. Pre- and post-conditioning (one's complement) is performed within this
function so it shouldn't be done by the application.

* struct drm_mode_fb_cmd2 - Frame-buffer metadata.
*
* This struct holds frame-buffer metadata. There are two ways to use it:
*
* - User-space can fill this struct and perform a &DRM_IOCTL_MODE_ADDFB2
* ioctl to register a new frame-buffer. The new frame-buffer object ID will
* be set by the kernel in @fb_id.
* - User-space can set @fb_id and perform a &DRM_IOCTL_MODE_GETFB2 ioctl to
* fetch metadata about an existing frame-buffer.
*
* In case of planar formats, this struct allows up to 4 buffer objects with
* offsets and pitches per plane. The pitch and offset order are dictated by
* the format FourCC as defined by ``drm_fourcc.h``, e.g. NV12 is described as:
*
* YUV 4:2:0 image with a plane of 8-bit Y samples followed by an
* interleaved U/V plane containing 8-bit 2x2 subsampled colour difference
* samples.
*
* So it would consist of a Y plane at ``offsets[0]`` and a UV plane at
* ``offsets[1]``.
*
* To accommodate tiled, compressed, etc formats, a modifier can be specified.
* For more information see the "Format Modifiers" section. Note that even
* though it looks like we have a modifier per-plane, we in fact do not. The
* modifier for each plane must be identical. Thus all combinations of
* different data layouts for multi-plane formats must be enumerated as
* separate modifiers.
*
* All of the entries in @handles, @pitches, @offsets and @modifier must be
* zero when unused. Warning, for @offsets and @modifier zero can't be used to
* figure out whether the entry is used or not since it's a valid value (a zero
* offset is common, and a zero modifier is &DRM_FORMAT_MOD_LINEAR).

* This queries metadata about a framebuffer. User-space fills
* &drm_mode_fb_cmd2.fb_id as the input, and the kernels fills the rest of the
* struct as the output.
*
* If the client is DRM master or has &CAP_SYS_ADMIN, &drm_mode_fb_cmd2.handles
* will be filled with GEM buffer handles. Fresh new GEM handles are always
* returned, even if another GEM handle referring to the same memory object
* already exists on the DRM file description. The caller is responsible for
* removing the new handles, e.g. via the &DRM_IOCTL_GEM_CLOSE IOCTL. The same
* new handle will be returned for multiple planes in case they use the same
* memory object. Planes are valid until one has a zero handle -- this can be
* used to compute the number of planes.
*
* Otherwise, &drm_mode_fb_cmd2.handles will be zeroed and planes are valid
* until one has a zero &drm_mode_fb_cmd2.pitches.
*
* If the framebuffer has a format modifier, &DRM_MODE_FB_MODIFIERS will be set
* in &drm_mode_fb_cmd2.flags and &drm_mode_fb_cmd2.modifier will contain the
* modifier. Otherwise, user-space must ignore &drm_mode_fb_cmd2.modifier.
*
* To obtain DMA-BUF FDs for each plane without leaking GEM handles, user-space
* can export each handle via &DRM_IOCTL_PRIME_HANDLE_TO_FD, then immediately
* close each unique handle via &DRM_IOCTL_GEM_CLOSE, making sure to not
* double-close handles which are specified multiple times in the array.

/**
* struct i915_user_extension - Base class for defining a chain of extensions
*
* Many interfaces need to grow over time. In most cases we can simply
* extend the struct and have userspace pass in more data. Another option,
* as demonstrated by Vulkan's approach to providing extensions for forward
* and backward compatibility, is to use a list of optional structs to
* provide those extra details.
*
* The key advantage to using an extension chain is that it allows us to
* redefine the interface more easily than an ever growing struct of
* increasing complexity, and for large parts of that interface to be
* entirely optional. The downside is more pointer chasing; chasing across
* the boundary with pointers encapsulated inside u64.
*
* Example chaining:
*
* .. code-block:: C
*
* struct i915_user_extension ext3 {
* .next_extension = 0, // end
* .name = ...,
* };
* struct i915_user_extension ext2 {
* .next_extension = (uintptr_t)&ext3,
* .name = ...,
* };
* struct i915_user_extension ext1 {
* .next_extension = (uintptr_t)&ext2,
* .name = ...,
* };
*
* Typically the struct i915_user_extension would be embedded in some uAPI
* struct, and in this case we would feed it the head of the chain(i.e ext1),
* which would then apply all of the above extensions.

* DOC: Virtual Engine uAPI
*
* Virtual engine is a concept where userspace is able to configure a set of
* physical engines, submit a batch buffer, and let the driver execute it on any
* engine from the set as it sees fit.
*
* This is primarily useful on parts which have multiple instances of a same
* class engine, like for example GT3+ Skylake parts with their two VCS engines.
*
* For instance userspace can enumerate all engines of a certain class using the
* previously described `Engine Discovery uAPI`_. After that userspace can
* create a GEM context with a placeholder slot for the virtual engine (using
* `I915_ENGINE_CLASS_INVALID` and `I915_ENGINE_CLASS_INVALID_NONE` for class
* and instance respectively) and finally using the
* `I915_CONTEXT_ENGINES_EXT_LOAD_BALANCE` extension place a virtual engine in
* the same reserved slot.
*

*
* .. code-block:: C

* N buffer objects or first N if I915_EXEC_BATCH_FIRST is set.
*
* The default placement behavior is to create implicit bonds between each

* DOC: Engine Discovery uAPI
*
* Engine discovery uAPI is a way of enumerating physical engines present in a
* GPU associated with an open i915 DRM file descriptor. This supersedes the old
* way of using `DRM_IOCTL_I915_GETPARAM` and engine identifiers like
* `I915_PARAM_HAS_BLT`.
*
* The need for this interface came starting with Icelake and newer GPUs, which
* started to establish a pattern of having multiple engines of a same class,
* where not all instances were always completely functionally equivalent.
*
* Entry point for this uapi is `DRM_IOCTL_I915_QUERY` with the
* `DRM_I915_QUERY_ENGINE_INFO` as the queried item id.
*
* Example for getting the list of engines:
*
* .. code-block:: C
*
* struct drm_i915_query_engine_info *info;
* struct drm_i915_query_item item = {
* .query_id = DRM_I915_QUERY_ENGINE_INFO;
* };
* struct drm_i915_query query = {
* .num_items = 1,
* .items_ptr = (uintptr_t)&item,
* };
* int err, i;
*
* // First query the size of the blob we need, this needs to be large
* // enough to hold our array of engines. The kernel will fill out the
* // item.length for us, which is the number of bytes we need.
* //
* // Alternatively a large buffer can be allocated straightaway enabling
* // querying in one pass, in which case item.length should contain the
* // length of the provided buffer.
* err = ioctl(fd, DRM_IOCTL_I915_QUERY, &query);
* if (err) ...
*
* info = calloc(1, item.length);
* // Now that we allocated the required number of bytes, we call the ioctl
* // again, this time with the data_ptr pointing to our newly allocated
* // blob, which the kernel can then populate with info on all engines.
* item.data_ptr = (uintptr_t)&info;
*
* err = ioctl(fd, DRM_IOCTL_I915_QUERY, &query);
* if (err) ...
*
* // We can now access each engine in the array
* for (i = 0; i < info->num_engines; i++) {
* struct drm_i915_engine_info einfo = info->engines[i];
* u16 class = einfo.engine.class;
* u16 instance = einfo.engine.instance;
* ....
* }
*
* free(info);
*
* Each of the enumerated engines, apart from being defined by its class and
* instance (see `struct i915_engine_class_instance`), also can have flags and
* capabilities defined as documented in i915_drm.h.
*
* For instance video engines which support HEVC encoding will have the
* `I915_VIDEO_CLASS_CAPABILITY_HEVC` capability bit set.
*
* Engine discovery only fully comes to its own when combined with the new way
* of addressing engines when submitting batch buffers using contexts with

*
* Only valid when placing objects in I915_MEMORY_CLASS_DEVICE, and only
* strictly required on configurations where some subset of the device
* memory is directly visible/mappable through the CPU (which we also
* call small BAR), like on some DG2+ systems. Note that this is quite

* it's something we can expect to see in the wild. See
* &drm_i915_memory_region_info.probed_cpu_visible_size for how to
* determine if this system applies.
*
* Note that one of the placements MUST be I915_MEMORY_CLASS_SYSTEM, to
* ensure the kernel can always spill the allocation to system memory,
* if the object can't be allocated in the mappable part of
* I915_MEMORY_CLASS_DEVICE.
*
* Also note that since the kernel only supports flat-CCS on objects
* that can *only* be placed in I915_MEMORY_CLASS_DEVICE, we therefore
* don't support I915_GEM_CREATE_EXT_FLAG_NEEDS_CPU_ACCESS together with
* flat-CCS.
*
* Without this hint, the kernel will assume that non-mappable
* I915_MEMORY_CLASS_DEVICE is preferred for this object. Note that the
* kernel can still migrate the object to the mappable part, as a last
* resort, if userspace ever CPU faults this object, but this might be
* expensive, and so ideally should be avoided.
*
* On older kernels which lack the relevant small-bar uAPI support (see
* also &drm_i915_memory_region_info.probed_cpu_visible_size),
* usage of the flag will result in an error, but it should NEVER be
* possible to end up with a small BAR configuration, assuming we can
* also successfully load the i915 kernel module. In such cases the

* query the supported regions for a device.
*
* As an example, on discrete devices, if we wish to set the placement as
* device local-memory we can do something like:
*
* .. code-block:: C
*
* struct drm_i915_gem_memory_class_instance region_lmem = {
* .memory_class = I915_MEMORY_CLASS_DEVICE,
* .memory_instance = 0,
* };
* struct drm_i915_gem_create_ext_memory_regions regions = {
* .base = { .name = I915_GEM_CREATE_EXT_MEMORY_REGIONS },
* .regions = (uintptr_t)&region_lmem,
* .num_regions = 1,
* };
* struct drm_i915_gem_create_ext create_ext = {
* .size = 16 * PAGE_SIZE,
* .extensions = (uintptr_t)&regions,
* };
*
* int err = ioctl(fd, DRM_IOCTL_I915_GEM_CREATE_EXT, &create_ext);
* if (err) ...
*
* At which point we get the object handle in &drm_i915_gem_create_ext.handle,
* along with the final object size in &drm_i915_gem_create_ext.size, which
* should account for any rounding up, if required.
*
* Note that userspace has no means of knowing the current backing region
* for objects where @num_regions is larger than one. The kernel will only
* ensure that the priority order of the @regions array is honoured, either
* when initially placing the object, or when moving memory around due to
* memory pressure
*
* On Flat-CCS capable HW, compression is supported for the objects residing
* in I915_MEMORY_CLASS_DEVICE. When such objects (compressed) have other
* memory class in @regions and migrated (by i915, due to memory
* constraints) to the non I915_MEMORY_CLASS_DEVICE region, then i915 needs to
* decompress the content. But i915 doesn't have the required information to
* decompress the userspace compressed objects.
*
* So i915 supports Flat-CCS, on the objects which can reside only on
* I915_MEMORY_CLASS_DEVICE regions.

/* Describe the long-named options requested by the application.
The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector
of 'struct option' terminated by an element containing a name which is
zero.
The field 'has_arg' is:
no_argument (or 0) if the option does not take an argument,
required_argument (or 1) if the option requires an argument,
optional_argument (or 2) if the option takes an optional argument.
If the field 'flag' is not NULL, it points to a variable that is set
to the value given in the field 'val' when the option is found, but
left unchanged if the option is not found.
To have a long-named option do something other than set an 'int' to
a compiled-in constant, such as set a value from 'optarg', set the
option's 'flag' field to zero and its 'val' field to a nonzero
value (the equivalent single-letter option character, if there is
one). For long options that have a zero 'flag' field, 'getopt'
returns the contents of the 'val' field. */

*
* This is a magic control flow block which denotes a subtest code
* block that contains dynamic subsubtests. The _f variant accepts a
* printf format string, which is useful for constructing
* combinatorial tests.
*
* Dynamic subsubtests are to be used when reporting several aspects
* of something separately is desired, but knowing the full possible
* set beforehand is either too big of a set or just plain
* impossible. Otherwise, use normal subtests. An easy example is
* performing an operation separately for each KMS pipe: A subtest per
* pipe requires iterating through all possible pipe identifiers,
* checking if the pipe exists for the tested device and skipping if
* does not, and then performing the operation. With dynamic
* subsubtests instead, there would be a single subtest for the
* operation that loops over the pipes available, enters a dynamic
* subsubtest for each pipe and performs the operation for that pipe
* in there.
*
* The result of a subtest igt_subtest_with_dynamic will be
* * SKIP, if no dynamic subsubtests are entered
* * PASS, if _all_ dynamic subsubtests PASS
* * FAIL, if _any_ dynamic subsubtests FAIL
*
* Within a igt_subtest_with_dynamic block, explicit
* failure (e.g. igt_assert) is not allowed, only dynamic subsubtests
* themselves will produce test results. igt_skip()/igt_require() is
* allowed. Example:
*
* |[<!-- language="C" -->
* igt_main
* {
* igt_subtest_with_dynamic("engine-tests") {
* igt_require(is_awesome(fd)); // requires ok here
*
* for_each_engine(fd, e) {
* igt_dynamic_subtest_f("%s", e->name) {
* igt_assert(works(e)); // asserts ok here
* }
