Debian                                          December 18, 2017                       ZIP_SOURCE_SEEK_WRITE(3)

       The  function  zip_source_seek_write()  sets the current write offset for source.  Just like in fseek(3),
       depending on the whence argument, the offset is counted relative from:

             SEEK_SET    start of file

             SEEK_CUR    current write offset in file

             SEEK_END    end of file

zip_source_seek_write() was added in libzip 1.0.

       libzip (-lzip)

       Upon successful completion 0 is returned.  Otherwise, -1 is returned and the error information in  source
       is set to indicate the error.
