This header file defines a debugging aid. | |
As there is no standard error output stream available for many | |
applications using this library, the generation of a printable | |
error message is not enabled by default. These messages will | |
only be generated if the application defines the macro | |
\code __ASSERT_USE_STDERR \endcode | |
before including the \c <assert.h> header file. By default, | |
only abort() will be called to halt the application. | |

/** | |
* \def assert | |
* \param expression Expression to test for. | |
* | |
* The assert() macro tests the given expression and if it is false, | |
* the calling process is terminated. A diagnostic message is written | |
* to stderr and the function abort() is called, effectively | |
* terminating the program. | |
* | |
* If expression is true, the assert() macro does nothing. | |
* | |
* The assert() macro may be removed at compile time by defining | |
* NDEBUG as a macro (e.g., by using the compiler option -DNDEBUG). | |
