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_by_code()
             Enables a single filter specified by the filter code.  This func-
             tion does not work with ARCHIVE_FILTER_PROGRAM.  Note: In stati-
             cally-linked executables, this will cause your program to include
             support for every filter.  If executable size is a concern, you
             may wish to avoid using this function.
     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 con-
             junction 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.
