Cleaning up the exit execution environment

 

While processing an explicit MQDISC call, or an implicit disconnect request as a result of an application ending, exit handling logic might need to clean up the exit execution environment after invoking the exit termination function (MQ_TERM_EXIT), if registered. Cleaning up the exit execution environment involves releasing storage for exit parameter structures, possibly deleting any modules previously loaded into memory.

If errors occur during this phase, an explicit MQDISC call fails with CompCode MQCC_FAILED and the following reason code (errors are not highlighted on implicit disconnect requests):

MQRC_API_EXIT_TERM_ERROR

An error was encountered while closing the execution environment for an API exit function. The exit should not return any failure from the MQDISC before or after the MQ_TERM* API exit function calls.
