Controlling context information

 

To control context information, use the Options field in the MQPMO structure.

If you do not, the queue manager overwrites context information that might already be in the message descriptor with the identity and context information that it has generated for your message. This is the same as specifying the MQPMO_DEFAULT_CONTEXT option. You might want this default context information when you create a new message (for example, when processing user input from an inquiry screen).

If you want no context information associated with your message, use the MQPMO_NO_CONTEXT option.
