1mDESCRIPTION0m
       1marchive_read_support_filter_bzip222m(),
	       1marchive_read_support_filter_compress22m(),
	       1marchive_read_support_filter_grzip22m(),
	       1marchive_read_support_filter_gzip22m(),
	       1marchive_read_support_filter_lrzip22m(),
	       1marchive_read_support_filter_lz422m(),
	       1marchive_read_support_filter_lzma22m(),
	       1marchive_read_support_filter_lzop22m(),
	       1marchive_read_support_filter_none22m(),
	       1marchive_read_support_filter_rpm22m(),
	       1marchive_read_support_filter_uu22m(),
	       1marchive_read_support_filter_xz22m(),
	       1marchive_read_support_filter_zstd22m(),
	       Enables	auto-detection	code and decompression support for the
	       specified compression.  These functions may fall back on exter‐
	       nal 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.
       1marchive_read_support_filter_all22m()
	       Enables all available decompression filters.
       1marchive_read_support_filter_by_code22m()
	       Enables a single filter specified by  the  filter  code.	  This
	       function	 does  not work with 1mARCHIVE_FILTER_PROGRAM22m.  Note: In
	       statically-linked executables, this will cause your program  to
	       include support for every filter.  If executable size is a con‐
	       cern, you may wish to avoid using this function.
       1marchive_read_support_filter_program22m()
	       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.
       1marchive_read_support_filter_program_signature22m()
	       This feeds data through the specified external program but only
	       if the initial bytes of the data match the specified  signature
	       value.

1mRETURN VALUES0m
       These  functions	 return	 1mARCHIVE_OK  22mif  the compression is fully sup‐
       ported, 1mARCHIVE_WARN 22mif the compression is supported  only	through	 an
       external program, or 1mARCHIVE_FATAL 22mon error.

       1marchive_read_support_filter_none22m() always succeeds.

1mERRORS0m
       Detailed	 error	codes  and textual descriptions are available from the
       1marchive_errno22m() and 1marchive_error_string22m() functions.
