zip_close

zip_close —
close zip archive

libzip (-lzip)

#include <zip.h>

int
zip_close(zip_t *archive);

The zip_close() function writes any changes made to archive to disk. If archive contains no files, the file is completely removed (no empty archive is written), unless the archive flag ZIP_AFL_CREATE_OR_KEEP_FILE_FOR_EMPTY_ARCHIVE is set. If successful, archive is freed. Otherwise archive is left unchanged and must still be freed.

To close and free a zip archive without saving changes, use zip_discard(3).

Progress updates for GUIs can be implemented using zip_register_progress_callback_with_state(3). Cancelling the write of an archive during zip_close can be implemented using zip_register_cancel_callback_with_state(3).

Upon successful completion 0 is returned. Otherwise, -1 is returned and the error code in archive is set to indicate the error.

zip_close() will fail if:
[]
Unexpected end-of-file found while reading from a file.
[]
The callback function of an added or replaced file returned an error but failed to report which.
[]
The path argument is NULL.
[]
Required memory could not be allocated.
[]
File is not a zip archive.
[]
A file read failed.
[]
A temporary file could not be renamed to its final name.
[]
A file seek failed.
[]
A temporary file could not be created.
[]
A file write failed.
[]
An error occurred while (de)compressing a stream with zlib(3).
Additionally, any errors returned by the callback function for added or replaced files will be passed back.

zip_close() was added in libzip 0.6.

Please note that all indices, zip_stat(3) information and other data about the archive is invalid after zip_close. When you open the same file again, it will be a completely new zip_t structure.
