Debian                                           August 19, 2022                          ZIP_GET_NUM_ENTRIES(3)

       The  zip_get_num_entries() function returns the number of entries in archive.  Entries are all files that
       are present in the original archive or that were added while the archive is open.  This includes  deleted
       files,  since  indices  are  not  renumbered  until  the archive is closed.  (This allows one to refer to
       deleted files, e. g. to undelete them.)

       If flags is set to ZIP_FL_UNCHANGED, the original number of files is returned.

zip_get_num_entries() was added in libzip 0.10.   In  libzip  0.11  the  return  type  was  changed  from
       zip_uint64_t to zip_int64_t.  In libzip 0.11 the type of flags was changed from int to zip_flags_t.
