DESCRIPTION

       archive_read_support_filter_bzip2(),                              archive_read_support_filter_compress(),
               archive_read_support_filter_grzip(),                          archive_read_support_filter_gzip(),
               archive_read_support_filter_lrzip(),                           archive_read_support_filter_lz4(),
               archive_read_support_filter_lzma(),                           archive_read_support_filter_lzop(),
               archive_read_support_filter_none(),                            archive_read_support_filter_rpm(),
               archive_read_support_filter_uu(),                               archive_read_support_filter_xz(),
               archive_read_support_filter_zstd(),
               Enables  auto-detection  code  and  decompression  support  for the specified compression.  These
               functions may fall back on external programs if an appropriate library was not available at build
               time.  Decompression using an external program  is  usually  slower  than  decompression  through
               built-in libraries.  Note that “none” is always enabled by default.
       archive_read_support_filter_all()
               Enables all available decompression filters.
       archive_read_support_filter_program()
               Data  is  fed  through  the  specified  external program before being dearchived.  Note that this
               disables automatic detection of the compression format, so it makes no sense to specify  this  in
               conjunction with any other decompression option.
       archive_read_support_filter_program_signature()
               This  feeds data through the specified external program but only if the initial bytes of the data
               match the specified signature value.

RETURN VALUES

       These functions return ARCHIVE_OK if the compression is fully supported, ARCHIVE_WARN if the  compression
       is supported only through an external program.

       archive_read_support_filter_none() always succeeds.

ERRORS

       Detailed   error   codes   and   textual   descriptions   are  available  from  the  archive_errno()  and
       archive_error_string() functions.
