| .SH DESCRIPTION |
| 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. |
| .LP |
| Notifiers \fBMUST\fR read IPP messages from the standard input using the |
| .BR ippNew () |
| and |
| .BR 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. |
| Notifiers inherit the environment and can use the logging mechanism documented in |
| .BR filter (7). |
