6 qb_log_filter_fn_set - Instead of using the qb_log_filter_ctl() func‐
7 tions you can apply the filters manually by defining a callback and
8 setting the targets field using qb_bit_set() and qb_bit_clear() like
9 the following below:

11
13 #include <qb/qblog.h>
14
15 int32_t qb_log_filter_fn_set(
16 qb_log_filter_fn fn
17 );
18
20 static void
21 m_filter(struct qb_log_callsite *cs)
22 {
23 if ((cs->priority >= LOG_ALERT &&
24 cs->priority <= LOG_DEBUG) &&
25 strcmp(cs->filename, "my_c_file.c") == 0) {
26 qb_bit_set(cs->targets, QB_LOG_SYSLOG);
27 } else {
28 qb_bit_clear(cs->targets, QB_LOG_SYSLOG);
29 }
