           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
            * "%g" in the format specifer to print it out.

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.
