NAME
log, addlog
— log a message from the kernel
through the /dev/klog device
SYNOPSIS
#include
<sys/syslog.h>
void
log(int level,
const char *format, ...);
void
addlog(const
char *format,
...);
DESCRIPTION
The
log()
function allows the kernel to send formatted 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 formatted using
printf(9), logged using facility LOG_KERN,
and priority level level.
The
addlog()
function is used to build a log message in steps, by adding information to
an initial call to log().
