Syslog Example (The GNU C Library)

#### 18.2.5 Syslog Example ¶

Here is an example of `openlog`, `syslog`, and `closelog`:

This example sets the logmask so that debug and informational messages get discarded without ever reaching Syslog. So the second `syslog` in the example does nothing.

    #include <syslog.h>

    setlogmask (LOG_UPTO (LOG_NOTICE));

    openlog ("exampleprog", LOG_CONS | LOG_PID | LOG_NDELAY, LOG_LOCAL1);

    syslog (LOG_NOTICE, "Program started by User %d", getuid ());
    syslog (LOG_INFO, "A tree falls in a forest");

    closelog ();
