SYSLOG(3C)              COMMAND REFERENCE              SYSLOG(3C)



NAME
     syslog, openlog, closelog - control system log

SYNOPSIS
     #include <syslog.h>

     openlog(ident, logstat)
     char *ident;

     syslog(priority, message, parameters ... )
     char *message;

     closelog()

DESCRIPTION
     Syslog arranges to write the message onto the system log
     maintained by syslog(8).  The message is tagged with
     priority.  The message looks like a printf(3) string except
     that %m is replaced by the current error message (collected
     from errno).  A trailing newline is added if needed.  This
     message will be read by syslog(8) and output to the system
     console or files as appropriate.

     If special processing is needed, openlog can be called to
     initialize the log file.  Parameters are ident which is
     prepended to every message, and logstat which is a bit field
     indicating special status; current values are:

     LOG_PID log the process ID with each message: useful for
             identifying instances of daemons.

     Openlog returns zero (0) on success.  If it cannot open the
     file /dev/log, it writes on /dev/console instead and returns
     -1.

     Closelog can be used to close the log file.

EXAMPLES
          syslog(LOG_SALERT, "who: internal error 23");

          openlog("serverftp", LOG_PID);
          syslog(LOG_INFO, "Connection from host %d", CallingHost);


CAVEATS
     If you elect to have your messages sent to the standard
     system log as specified in the configuration file (see
     syslog(8)) and the daemon, /etc/syslog is not running, your
     program will be sent a SIGPIPE (see sigvec(2)) on the second
     call to syslog.
