NAME    [Toc]    [Back]

     log, addlog - log a message  from  the  kernel  through  the
/dev/klog device

SYNOPSIS    [Toc]    [Back]

     #include <sys/syslog.h>

     void
     log(int level, const char *format, ...);

     void
     addlog(const char *format, ...);

DESCRIPTION    [Toc]    [Back]

     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().
