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);
               }
       }
