19The CUPS notifier interface provides a standard method for adding support for new event notification methods to CUPS.
20Each notifier delivers one or more IPP events from the standard input to the specified recipient.
21<p>Notifiers <b>MUST</b> read IPP messages from the standard input using the
22<b>ippNew</b>()
23and
24<b>ippReadFile</b>()
25functions and exit on error.
26Notifiers 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.
27Notifiers inherit the environment and can use the logging mechanism documented in
28<b>filter</b>(7).
