NAME

zip_unchange —

undo changes to file in zip archive

LIBRARY

libzip (-lzip)

#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.

zip_unchange() was added in libzip 0.6. In libzip 0.10 the type of index was changed from int to zip_uint64_t.
