LOG(9) FreeBSD Kernel Developer's Manual LOG(9)
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().
