DESCRIPTION

    archive_write_add_filter_bzip2(), archive_write_add_filter_compress(), archive_write_add_filter_grzip(), archive_write_add_filter_gzip(), archive_write_add_filter_lrzip(), archive_write_add_filter_lz4(), archive_write_add_filter_lzip(), archive_write_add_filter_lzma(), archive_write_add_filter_lzop(), archive_write_add_filter_xz(), archive_write_add_filter_zstd(), The resulting archive will be compressed as specified. Note that the compressed output is always properly blocked.

    archive_write_add_filter_b64encode(), archive_write_add_filter_uuencode(), The output will be encoded as specified. The encoded output is always properly blocked.

archive_write_add_filter_none()
    This is never necessary. It is provided only for backwards compatibility.

archive_write_add_filter_program()
    The archive will be fed into the specified compression program. The output of that program is blocked and written to the client write callbacks.

RETURN VALUES
These functions return ARCHIVE_OK on success, or ARCHIVE_FATAL.

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