Backing out changes using the MQBACK call

 

As input, supply a connection handle (Hconn). Use the handle that is returned by the MQCONN or MQCONNX call.

The output from MQBACK is a completion code and a reason code.

The output indicates to the queue manager that the application has reached a syncpoint and that all gets and puts that have been made since the last syncpoint have been backed out.

There is a description of the MQBACK call in the Application Programming Reference.
