ZIP_FILE_SET_MTIME(3) Library Functions Manual ZIP_FILE_SET_MTIME(3)

set last modification time (mtime) for file in zip

libzip (-lzip)

#include <zip.h>

zip_file_set_mtime(zip_t *archive, zip_uint64_t index, time_t mtime, zip_flags_t flags);

The zip_file_set_mtime() function sets the last modification time (mtime) for the file at position index in the zip archive to mtime. Currently, no support for any flags is implemented.

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

zip_file_set_mtime() fails if:
index is not a valid file index in archive.
Required memory could not be allocated.
The archive was opened in read-only mode.

libzip(3), zip_stat(3)

zip_file_set_mtime() was added in libzip 1.0.
