ARCHIVE_READ_FILTER(3) BSD Library Functions Manual ARCHIVE_READ_FILTER(3) NAME archive_read_support_filter_all, archive_read_support_filter_bzip2, archive_read_support_filter_compress, archive_read_support_filter_gzip, archive_read_support_filter_lz4, archive_read_support_filter_lzma, 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, archive_read_support_filter_program, archive_read_support_filter_program_signature -- functions for reading streaming archives LIBRARY Streaming Archive Library (libarchive, -larchive) SYNOPSIS #include <archive.h> int archive_read_support_filter_all(struct archive *); int archive_read_support_filter_by_code(struct archive *, int); int archive_read_support_filter_bzip2(struct archive *); int archive_read_support_filter_compress(struct archive *); int archive_read_support_filter_grzip(struct archive *); int archive_read_support_filter_gzip(struct archive *); int archive_read_support_filter_lrzip(struct archive *); int archive_read_support_filter_lz4(struct archive *); int archive_read_support_filter_lzma(struct archive *); int archive_read_support_filter_lzop(struct archive *); int archive_read_support_filter_none(struct archive *); int archive_read_support_filter_rpm(struct archive *); int archive_read_support_filter_uu(struct archive *); int archive_read_support_filter_xz(struct archive *); int archive_read_support_filter_zstd(struct archive *); int archive_read_support_filter_program(struct archive *, const char *cmd); int archive_read_support_filter_program_signature(struct archive *, const char *cmd, const void *signature, size_t signature_length); 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.
