Requesting that a Message Be Completed

IXCMSGC allows a user to force the message to be immediately considered complete. The member invoking the IXCMSGC Completion service must be the same member that sent the message to be completed. Use the IXCMSGC Completion service for a message-out request that XCF has accepted for delivery, but does not consider complete. See Understanding Message Completion for a description of when a message is considered complete.

When the IXCMSGC Completion service returns to the member, the message is known to be complete and processing for the message continues just as it would have had the message completed without IXCMSGC intervention. That processing includes:

XCF no longer attempts to send the message to any intended target.
XCF discards any responses to the message that arrive subsequent to its completion. (Responses that are not collected are identified with the MNPLKRESPCODETOOLATE return code in the MNPL for the appropriate target entry.)
If XCF was to initiate notification upon completion of the message, the message notify user routine receives control. If not, the member can invoke the IXCMSGC Call Exit service to call a message notify user routine to process the completed message.
