DESCRIPTION

     archive_read_support_filter_bzip2(), archive_read_support_filter_compress(),
             archive_read_support_filter_gzip(), archive_read_support_filter_lzma(),
             archive_read_support_filter_none(), 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.
