PTMAP provides functions to cancel outstanding requests. When a request has been sent to the PTMRP, the application is considered to have an outstanding request until PTMRP responds. "On-Alarm", "On-Acknowledge", or "On-Change" requests cause the application to have outstanding requests until the request has been canceled.

Applications must cancel requests to stop the PTMRP from responding to the request. Responses received prior to the cancellation of the request must be processed before deleting that request using PTMAP_get functions.

The subroutines are:

PTMAP_cancel_req	Cancel A Single Request
PTMAP_cancel_sl	Cancel Requests For A Shopping List
PTMAP_cancel_all	Cancel All Outstanding Requests
PTMAP_cancel_point	Cancel Requests For A Point
