-=head1 NAME
-
-Sys::Syslog, openlog, closelog, setlogmask, syslog - Perl interface to the UNIX syslog(3) calls
-
-=head1 SYNOPSIS
-
- use Sys::Syslog; # all except setlogsock, or:
- use Sys::Syslog qw(:DEFAULT setlogsock); # default set, plus setlogsock
-
- setlogsock $sock_type;
- openlog $ident, $logopt, $facility;
- syslog $priority, $format, @args;
- $oldmask = setlogmask $mask_priority;
- closelog;
-
-=head1 DESCRIPTION
-
-Sys::Syslog is an interface to the UNIX C<syslog(3)> program.
-Call C<syslog()> with a string priority and a list of C<printf()> args
-just like C<syslog(3)>.
-
-Syslog provides the functions:
-
-=over
-
-=item openlog $ident, $logopt, $facility
-
-I<$ident> is prepended to every message.
-I<$logopt> contains zero or more of the words I<pid>, I<ndelay>, I<cons>, I<nowait>.
-I<$facility> specifies the part of the system
-
-=item syslog $priority, $format, @args
-
-If I<$priority> permits, logs I<($format, @args)>
-printed as by C<printf(3V)>, with the addition that I<%m>
-is replaced with C<"$!"> (the latest error message).
-
-=item setlogmask $mask_priority
-
-Sets log mask I<$mask_priority> and returns the old mask.
-
-=item setlogsock $sock_type (added in 5.004_02)
-
-Sets the socket type to be used for the next call to
-C<openlog()> or C<syslog()> and returns TRUE on success,
-undef on failure.
-
-A value of 'unix' will connect to the UNIX domain socket returned by the
-C<_PATH_LOG> macro (if you system defines it) in F<syslog.h>. A value of
-'inet' will connect to an INET socket returned by getservbyname(). If
-C<_PATH_LOG> is unavailable or if getservbyname() fails, returns undef. Any
-other value croaks.
-
-The default is for the INET socket to be used.
-
-=item closelog
-
-Closes the log file.
-
-=back
-
-Note that C<openlog> now takes three arguments, just like C<openlog(3)>.
-
-=head1 EXAMPLES
-
- openlog($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)
