3.1.5.4 GetNotify Timer Event

The GetNotify timer (section 3.1.2.4) MUST be started when a protocol version 2.0 server processes an ApiGetNotify method, as specified in section 3.1.4.1.66. The expiration time of the GetNotify timer is designated by the Timeout parameter of the ApiGetNotify method.

When the GetNotify timer expires, the server MUST complete the associated ApiGetNotify method with the status WAIT_TIMEOUT (0x00000102). If the server completes the ApiGetNotify method for any other reason before the GetNotify timer expires (for instance, the server has an event indication to return to the client), then the server MUST cancel the GetNotify timer.
