CancelRtTransaction (deprecated)

From INtime 6.0 the INtime Service and Port objects have been deprecated.

New projects should not be started using these features, and existing projects will not work with XM mode. You will receive a compiler warning by default if you use these calls.

Performs synchronous cancellation of RSVP message transmission.

If a SendRtMessage or SendRtReply operation is canceled, then it must have returned a valid transaction ID, supplied as a parameter to cancel.

If cancellation of a SendRtMessageRSVP is successful, the reply buffer, if used, is disassociated from the port. Cancellation of a SendRtMessageRSVP operation is possible after the original request message transmission is complete and before a response message is received.
