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()
               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.
