zip_unchange — undo changes to file in zip archive
#include <zip.h> int zip_unchange(zip_t *archive, zip_uint64_t index);
Changes to the file at position index are reverted.
Upon successful completion 0 is returned. Otherwise, -1 is returned and the error code in archive is set to indicate the error.
zip_unchange() fails if: [ZIP_ER_EXISTS] Unchanging the name would result in a duplicate name in the archive. [ZIP_ER_INVAL] index is not a valid file index in zip.
libzip(3), zip_unchange_all(3), zip_unchange_archive(3)
zip_unchange() was added in libzip 0.6. In libzip 0.10 the type of index was changed from int to zip_uint64_t.
