Scriptable functions ==================== Network ------- .. function:: ntohs(netshort) This subroutine converts values between the host and network byte order. Specifically, **ntohs()** converts 16-bit quantities from network byte order to host byte order. :param netshort: 16-bit short addr :rtype: converted addr Cache ----- .. function:: storeQueryInCache(qstate, qinfo, msgrep, is_referral) Store pending query in local cache. :param qstate: :class:`module_qstate` :param qinfo: :class:`query_info` :param msgrep: :class:`reply_info` :param is_referal: integer :rtype: boolean .. function:: invalidateQueryInCache(qstate, qinfo) Invalidate record in local cache. :param qstate: :class:`module_qstate` :param qinfo: :class:`query_info` Logging ------- .. function:: verbose(level, msg) Log a verbose message, pass the level for this message. No trailing newline is needed. :param level: verbosity level for this message, compared to global verbosity setting. :param msg: string message .. function:: log_info(msg) Log informational message. No trailing newline is needed. :param msg: string message .. function:: log_err(msg) Log error message. No trailing newline is needed. :param msg: string message .. function:: log_warn(msg) Log warning message. No trailing newline is needed. :param msg: string message .. function:: log_hex(msg, data, length) Log a hex-string to the log. Can be any length. performs mallocs to do so, slow. But debug useful. :param msg: string desc to accompany the hexdump. :param data: data to dump in hex format. :param length: length of data. .. function:: log_dns_msg(str, qinfo, reply) Log DNS message. :param str: string message :param qinfo: :class:`query_info` :param reply: :class:`reply_info` .. function:: log_query_info(verbosity_value, str, qinf) Log query information. :param verbosity_value: see constants :param str: string message :param qinf: :class:`query_info` .. function:: regional_log_stats(r) Log regional statistics. :param r: :class:`regional` Debugging --------- .. function:: strextstate(module_ext_state) Debug utility, module external qstate to string. :param module_ext_state: the state value. :rtype: descriptive string. .. function:: strmodulevent(module_event) Debug utility, module event to string. :param module_event: the module event value. :rtype: descriptive string. .. function:: ldns_rr_type2str(atype) Convert RR type to string. .. function:: ldns_rr_class2str(aclass) Convert RR class to string.
