Examples

This section lists different examples for notification.

1. The following is an example of I_ERRLOG notification:

   
   struct strioctl ioc;
   ioc.ic_cmd = I_ERRLOG;
   ioc.ic_timout = 0;      /* default timeout (15 secs.)*/
   ioc.ic_len = 0;
   ioc.ic_dp = NULL;
   ioctl(log, I_STR, &ioc);
   

2. The following is an example of I_TRCLOG notification:

   
   struct trace_ids tid[2];
   tid[0].ti_mid = 2;
   tid[0].ti_sid = 0;
   tid[0].ti_level = 1;
   tid[1].ti_mid = 1002;
   tid[1].ti_sid = -1;   /* any sub-id will be allowed*/
   tid[1].ti_level = -1;  /* any level will be allowed*/
   ioc.ic_cmd = I_TRCLOG;
   ioc.ic_timeout = 0;
   ioc.ic_len = 2 * sizeof(struct trace_ids);
   ioc.ic_dp = (char *)tid;
   ioctl(log, I_STR, &ioc);
   

3. The following is an example of submitting a log message (no arguments):

   
   struct strbuf ctl, dat;
   struct log_ctl lc;
   char *message = "Honey, I'm working late again.";
   ctl.len = ctl.maxlen = sizeof(lc);
   ctl.buf = (char *)&lc;
   dat.len = dat.maxlen = strlen(message);
   dat.buf = message;
   lc.level = 0
   lc.flags = SL_ERROS;
   putmsg(log, &ctl, &dat, 0);
