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.
