LOG(9) | 
NAME
 log — log a message from the kernel through the /dev/klog device
SYNOPSIS
 #include <sys/syslog.h>
void
log(int level, const char *format, ...);
 
DESCRIPTION
 The 
log() function allows the kernel to send messages to user processes listening on 
/dev/klog. Usually 
syslogd(8) monitors 
/dev/klog for these messages and writes them to a log file.
All messages are logged using facility LOG_KERN. See syslog(3) for a listing of log levels.
