The IXCMSGC macro allows a cross-system coupling facility (XCF) application to interact with the XCF signalling services to provide additional functions. The IXCMSGC macro provides services that:

• Save a message for later processing
• Retrieve information about messages that have been saved or are pending completion
• Redeliver a message to the member that previously saved the message
• Cancel (discard) a pending message.
• Force a message to be considered complete
• Discard a message
• Release a client/server blocking receive request (IXCRECV), a client/server send message request (IXCSEND), or a message-out request (IXCMSGOX) issued with the MSGACCESS=SYNCSUSPEND keyword.
