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 function does
not work with
ARCHIVE_FILTER_PROGRAM. Note: In statically-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 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.
