=head1 NAME

Log::Dispatch::Syslog - Object for logging to system log.

=head1 VERSION

version 2.41

=head1 SYNOPSIS

use Log::Dispatch;

my $log = Log::Dispatch->new(
      outputs => [
          [
              'Syslog',
              min_level => 'info',
              ident     => 'Yadda yadda'
          ]
      ]
  );

$log->emerg("Time to die.");

=head1 DESCRIPTION

This module provides a simple object for sending messages to the
system log (via UNIX syslog calls).

Note that logging may fail if you try to pass UTF-8 characters in the
log message. If logging fails and warnings are enabled, the error
message will be output using Perl's C<warn>.

=head1 CONSTRUCTOR

The constructor takes the following parameters in addition to the standard
parameters documented in L<Log::Dispatch::Output>:

=over 4

=item * ident ($)

This string will be prepended to all messages in the system log.
Defaults to $0.

=item * logopt ($)

A string containing the log options (separated by any separator you
like).  See the openlog(3) and Sys::Syslog docs for more details.
Defaults to ''.

=item * facility ($)

Specifies what type of program is doing the logging to the system log.
Valid options are 'auth', 'authpriv', 'cron', 'daemon', 'kern',
'local0' through 'local7', 'mail', 'news', 'syslog', 'user',
'uucp'.  Defaults to 'user'

=item * socket ($ or \@)

Tells what type of socket to use for sending syslog messages.  Valid
options are listed in C<Sys::Syslog>.

If you don't provide this, then we let C<Sys::Syslog> simply pick one
that works, which is the preferred option, as it makes your code more
portable.

If you pass an array reference, it is dereferenced and passed to
C<Sys::Syslog::setlogsock()>.
