C++ (Cpp) log_enqueue Examples

Example #1

File: log_pthread.c Project: krisman/multipath-tools

void log_safe (int prio, const char * fmt, va_list ap)
{
	if (log_thr == (pthread_t)0) {
		vsyslog(prio, fmt, ap);
		return;
	}

	pthread_mutex_lock(&logq_lock);
	log_enqueue(prio, fmt, ap);
	pthread_mutex_unlock(&logq_lock);

	pthread_mutex_lock(&logev_lock);
	pthread_cond_signal(&logev_cond);
	pthread_mutex_unlock(&logev_lock);
}

Example #2

File: log.c Project: BackupTheBerlios/stgt-svn

{
	if (is_daemon) {
		la->ops[0].sem_op = -1;
		if (semop(la->semid, la->ops, 1) < 0) {

			return;
		}

		log_enqueue(prio, fmt, ap);

		la->ops[0].sem_op = 1;

			return;
		}
	} else {
		fprintf(stderr, "%s: ", log_name);
		vfprintf(stderr, fmt, ap);
		fflush(stderr);
