qb_log_from_external_source - This function is to import logs from other code (like libraries) that provide a callback with their logs.

#include <qb/qblog.h>

void qb_log_from_external_source(

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 */
uint32_t tags, /* this is a uint32_t that you can use with */
... );

priority this takes syslog priorities.

lineno file line number

tags this is a uint32_t that you can use with

(null)

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.
