const char *function, /* originating function name */
const char *filename, /* originating filename */
const char *format, /* format string */
uint8_t priority, /* this takes syslog priorities. */
uint32_t lineno, /* file line number */ /*
* this is a uint32_t that you can use with
* qb_log_tags_stringify_fn_set() to "tag" a log message with a feature or sub-system then you can use

DESCRIPTION¶
NOTE¶
the performance of this will not impress you, as the filtering is done on each log message, not beforehand. So try doing basic pre-filtering.
