NAME
       zip_set_file_compression - set compression method for file in zip


LIBRARY
       libzip (-lzip)


SYNOPSIS
       zip.h  int  zip_set_file_compression  zip_t  *archive  zip_uint64_t  index  zip_int32_t comp zip_uint32_t
       comp_flags


DESCRIPTION
       The zip_set_file_compression function sets the compression method for the file at position index  in  the
       zip archive to comp with the compression method specific comp_flags.  The comp is the same as returned by
       zip_stat(3).  For the comp argument, currently only the following values are supported:

       ZIP_CM_DEFAULT
              default compression; currently the same as ZIP_CM_DEFLATE.

       ZIP_CM_STORE
              Store the file uncompressed.

       ZIP_CM_DEFLATE
              Deflate the file with the zlib(3) algorithm and default options

       The comp_flags argument is currently ignored.

       The current compression method for a file in a zip archive can be determined using zip_stat(3).


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


ERRORS
       zip_set_file_compression fails if:

       [ZIP_ER_INVAL]   index is not a valid file index in archive, or the argument combination is invalid.

       [ZIP_ER_COMPNOTSUPP]
                        Unsupported compression method requested.

       [ZIP_ER_RDONLY]  Read-only zip file, no changes allowed.
