NAME

qb_log_filter_fn_set - Instead of using the qb_log_filter_ctl() functions you can apply the filters manually by defining a callback and setting the targets field using qb_bit_set() and qb_bit_clear() like the following below:

SYNOPSIS

#include <qb/qblog.h>

int32_t qb_log_filter_fn_set (
qb_log_filter_fn fn
);

DESCRIPTION

static void
m_filter(struct qb_log_callsite *cs)
{
if ((cs->priority >= LOG_ALERT &&
cs->priority <= LOG_DEBUG) &&
strcmp(cs->filename, "my_c_file.c") == 0) {
qb_bit_set(cs->targets, QB_LOG_SYSLOG);
} else {
qb_bit_clear(cs->targets, QB_LOG_SYSLOG);
}
}
