Sys::Syslog(3)

NAME
Sys::Syslog, openlog, closelog, setlogmask, syslog - Perl interface to the UNIX syslog(3) calls

SYNOPSIS

    use Sys::Syslog;
    openlog $ident, $logopt, $facility;
    syslog $priority, $format, @args;
    $oldmask = setlogmask $mask_priority;
    closelog;

DESCRIPTION
Sys::Syslog is an interface to the UNIX syslog(3) program. Call syslog() with a string priority and a list of printf() args just like syslog(3).

Syslog provides the functions: $ident is prepended to every message. $logopt contains one or more of the words pid, ndelay, cons, nowait. $facility specifies the part of the system If $priority permits, logs ($format, @args) printed as by printf(3V), with the addition that %m is replaced with "$!" (the latest error message). Sets log mask $mask_priority and returns the old mask. The default is for the INET socket to be used. Closes the log file.

Note that openlog now takes three arguments, just like openlog(3).

EXAMPLES

    openlog($program, 'cons,pid', 'user');
    syslog('info', 'this is another test');
    syslog('mail|warning', 'this is a better test: %d', time);
    closelog();
    syslog('debug', 'this is the last test');
    setlogsock('unix');
    openlog("$program $$", 'ndelay', 'user');
    syslog('notice', 'fooprogram: this is really done');
    setlogsock('inet');
    $! = 55;
    syslog('info', 'problem was %m'); # %m == $! in syslog(3)

DEPENDENCIES
Sys::Syslog needs syslog.ph, which can be created with h2ph.
