★ About API
Since it is in C format, when using it from C++, it is declared and used with extern "C"
Please do so. For structures, all are aligned to byte alignment.
It is necessary to define it (defined in YZ1.H).

Ordinal number 11
function

================================================== =====================
OpenArchive API
=================================================== =====================
1. In the explanation below
"The archive file" is the yz1 archive itself that is being operated.
"Stored file" is a file in the archive that matches the previous search.
The argument HARC arc is the handle returned by Yz1OpenArchive().
Refers to.
2. Precautions when operating the archive with password in OpenArchive system
If a password is applied to the yz1 library, you will have to enter it
Information on the stored file cannot be acquired. (Information on the archive file can be obtained.)
Refer to the explanation below and the explanation of the original API "Yz1Set/GetDefaultPassword",
Please implement in an appropriate form for the application.
*Operation inside Yz1OpenArchive*
If M_ERROR_MESSAGE_ON is set, Yz1SetDefaultPassword(arc,NULL);
If not, Yz1SetDefaultPassword(arc,""); is automatically executed.
*Operation when first Yz1FindFirst after OpenArchive of archive with path*
-The standard password is not set (==NULL).
Displays a password input dialog and prompts the user for input.
-A standard password is set.
Attempt to acquire information with the standard password.
as a result,
The password was correct.
The correct password is automatically saved with Yz1SetDefaultPassword(),
After that, it works the same as a normal archive.
The password was incorrect.
Search error returns ERROR_PASSWORD_FILE.
*Example*
1. Give up the information display of the archive with password easily.
OpenArchive() with M_ERROR_MESSAGE_OFF and the rest is normal.
.2. Give up, but please display the error message.
OpenArchive() with M_ERROR_MESSAGE_ON, then
Execute SetDefaultPassword(arc,"some dummy string"). The rest is normal.
3. If there is a password, have the user enter it at Find First.
OpenArchive() with M_ERROR_MESSAGE_ON and the rest is normal.
4. Please do not display the error message.
OpenArchive() with M_ERROR_MESSAGE_OFF, then
Execute SetDefaultPassword(arc,NULL). The rest is normal.
⑤ Since I call both FindFirst() and Yz1(),
I want to do it once without displaying the dialog.
First, check the return value of CheckArchive to see if it has a password.
<Properly if there is no password...>
If there is an I password, the application will display its own dialog and
Ask the user to enter a password.
Open with> Open Archive. (M_ERROR_MESSAGE_ON/OFF can be either)
Pass the previous password to SetDefaultPassword.
For example, FindFirst,
For example, pass the previous password to Yz1() with the -p option.
Another hand (only possible in the order of Yz1FindFirst -> Yz1)
First, open with OpenArchive and do FindFirst etc.
Get the password with GetDefaultPassword before CloseArchive,
Pass it to Yz1() with -p option.
