| Please do so. For structures, all are aligned to byte alignment. | |
| It is necessary to define it (defined in YZ1.H). | |

| ================================================== ===================== | |
| 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. | |
