<h2 class="title"><a name="DESCRIPTION">Description</a></h2>
The CUPS notifier interface provides a standard method for adding support for
new event notification methods to CUPS. Each notifier delivers one or more IPP
events from the standard input to the specified recipient.
<p>Notifiers <b>must</b> read IPP messages from the standard input using the
ippNew and ippReadFile functions and exit on error. Notifiers are encouraged to
exit after a suitable period of inactivity, however they may exit after reading
the first message or stay running until an error is seen.
<h2 class="title"><a name="LOG_MESSAGES">Log Messages</a></h2>
Messages sent to stderr are generally logged to the current <i>ErrorLog</i>.
Each line begins with a standard prefix:
