Debian                                         September 11, 2024                                   ZIP_FSEEK(3)

       The zip_fseek() function seeks to the specified offset relative to whence, just like fseek(3).

       zip_fseek  only works on uncompressed (stored), unencrypted data.  When called on compressed or encrypted
       data it will return an error.

       The zip_file_is_seekable() function returns 1 if a file is seekable.

zip_fseek() was added in libzip 1.2.0.  zip_file_is_seekable() was added in libzip 1.9.0.

       libzip (-lzip)

       zip_fseek, zip_file_is_seekable — seek in file

       If successful, zip_fseek() returns 0.  Otherwise, -1 is returned.

       zip_file_is_seekable() returns 1 if a file is seekable and 0 if not.  On an invalid argument, it  returns
       -1.
