Confirm Deallocate State

A TP enters Confirm Deallocate state from Receive state when it calls MCRcvAndWait or MCRcvNoWait and the WhatReceived parameter returns 7 (CONFIRM_DEALLOCATE). This indicates that the remote TP has issued the equivalent of the MCDeallocate intrinsic with a confirmation request.

Table 4-7 “Confirm Deallocate State Intrinsics” lists the intrinsics that can be called from Confirm Deallocate state. The MCDeallocate intrinsic can be called from Confirm Deallocate state only with the DeallocateType parameter set to 2 (ABEND). See the description of MCDeallocate in Chapter 5 “ Intrinsic Descriptions” for more information.
