  73 <p><code>Sys::Syslog</code> is an interface to the UNIX <a href="#item_syslog"><code>syslog(3)</code></a> program.
  74 Call <a href="#item_syslog"><code>syslog()</code></a> with a string priority and a list of <a href="file://C|\msysgit\mingw\html/pod/perlfunc.html#item_printf"><code>printf()</code></a> args

  79 <h1><a name="exports">EXPORTS</a></h1>
  80 <p><code>Sys::Syslog</code> exports the following <code>Exporter</code> tags:</p>
  81 <ul>
  82 <li>
  83 <p><code>:standard</code> exports the standard <a href="#item_syslog"><code>syslog(3)</code></a> functions:</p>
  84 <pre>
  85     openlog closelog setlogmask syslog</pre>
  86 </li>
  87 <li>
  88 <p><code>:extended</code> exports the Perl specific functions for <a href="#item_syslog"><code>syslog(3)</code></a>:</p>
  89 <pre>
  90     setlogsock</pre>
  91 </li>
  92 <li>
  93 <p><code>:macros</code> exports the symbols corresponding to most of your <a href="#item_syslog"><code>syslog(3)</code></a>
  94 macros. See <a href="#constants">CONSTANTS</a> for the supported constants and their meaning.</p>
  95 </li>

 104
 105 <dd>
 106 <p>Opens the syslog.
 107 <code>$ident</code> is prepended to every message.  <code>$logopt</code> contains zero or
 108 more of the words <code>pid</code>, <code>ndelay</code>, <code>nowait</code>.  The <code>cons</code> option is
 109 ignored, since the failover mechanism will drop down to the console
 110 automatically if all other media fail.  <code>$facility</code> specifies the
 111 part of the system to report about, for example <code>LOG_USER</code> or <code>LOG_LOCAL0</code>:
 112 see your <a href="#item_syslog"><code>syslog(3)</code></a> documentation for the facilities available in
 113 your system. Facility can be given as a string or a numeric macro.</p>
 114 </dd>
 115 <dd>
 116 <p>This function will croak if it can't connect to the syslog daemon.</p>
 117 </dd>
 118 <dd>
 119 <p>Note that <a href="#item_openlog"><code>openlog()</code></a> now takes three arguments, just like <a href="#item_openlog"><code>openlog(3)</code></a>.</p>
 120 </dd>
 121 <dd>
 122 <p><strong>You should use openlog() before calling syslog().</strong></p>

 124 <dd>
 125 <p><strong>Options</strong></p>
 126 </dd>
 127 <ul>
 128 <li>
 129 <p><code>ndelay</code> - Open the connection immediately (normally, the connection is
 130 opened when the first message is logged).</p>
 131 </li>
 132 <li>
 133 <p><code>nowait</code> - Don't wait for child processes that may have been created
 134 while logging the message.  (The GNU C library does not create a child
 135 process, so this option has no effect on Linux.)</p>
 136 </li>
 137 <li>
 138 <p><code>pid</code> - Include PID with each message.</p>
 139 </li>
 140 </ul>
 141 <p><strong>Examples</strong></p>
 142 <p>Open the syslog with options <code>ndelay</code> and <code>pid</code>, and with facility <code>LOCAL0</code>:</p>
 143 <pre>
 144     openlog($name, &quot;ndelay,pid&quot;, &quot;local0&quot;);</pre>
 145 <p>Same thing, but this time using the macro corresponding to <code>LOCAL0</code>:</p>

 154 with the addition that <code>%m</code> in $message or <code>$format</code> is replaced with
 155 <code>&quot;$!&quot;</code> (the latest error message).</p>
 156 </dd>
 157 <dd>
 158 <p><code>$priority</code> can specify a level, or a level and a facility.  Levels and
 159 facilities can be given as strings or as macros.</p>
 160 </dd>
 161 <dd>
 162 <p>If you didn't use <a href="#item_openlog"><code>openlog()</code></a> before using <a href="#item_syslog"><code>syslog()</code></a>, <a href="#item_syslog"><code>syslog()</code></a> will
 163 try to guess the <code>$ident</code> by extracting the shortest prefix of

 183 <p><code>Sys::Syslog</code> version v0.07 and older passed the <code>$message</code> as the
 184 formatting string to <code>sprintf()</code> even when no formatting arguments
 185 were provided.  If the code calling <a href="#item_syslog"><code>syslog()</code></a> might execute with
 186 older versions of this module, make sure to call the function as
 187 <a href="#item_syslog"><code>syslog($priority, &quot;%s&quot;, $message)</code></a> instead of <a href="#item_syslog"><code>syslog($priority,
 188 $message)</code></a>.  This protects against hostile formatting sequences that
