DESCRIPTION

69     archive_read_support_filter_bzip2(),
70             archive_read_support_filter_compress(),
71             archive_read_support_filter_grzip(),
72             archive_read_support_filter_gzip(),
73             archive_read_support_filter_lrzip(),
74             archive_read_support_filter_lz4(),
75             archive_read_support_filter_lzma(),
76             archive_read_support_filter_lzop(),
77             archive_read_support_filter_none(),
78             archive_read_support_filter_rpm(),
79             archive_read_support_filter_uu(),
80             archive_read_support_filter_xz(),
81             archive_read_support_filter_zstd(),
82             Enables auto-detection code and decompression support for the
83             specified compression.  These functions may fall back on external
84             programs if an appropriate library was not available at build
85             time.  Decompression using an external program is usually slower
86             than decompression through built-in libraries.  Note that “none”
87             is always enabled by default.
88     archive_read_support_filter_all()
89             Enables all available decompression filters.
90     archive_read_support_filter_program()
91             Data is fed through the specified external program before being
92             dearchived.  Note that this disables automatic detection of the
93             compression format, so it makes no sense to specify this in con‐
94             junction with any other decompression option.
95     archive_read_support_filter_program_signature()
96             This feeds data through the specified external program but only
97             if the initial bytes of the data match the specified signature
98             value.
99

RETURN VALUES

101     These functions return ARCHIVE_OK if the compression is fully supported,
102     ARCHIVE_WARN if the compression is supported only through an external
103     program.
104
105     archive_read_support_filter_none() always succeeds.
106

ERRORS

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