Debian                                          December 18, 2017                                ZIP_UNCHANGE(3)

       Changes to the file at position index are reverted.

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.
