This is an implementation function exported by the User Exit library (.lel). It is invoked just before unloading the .lel which typically happens when the execution group process is stopping. During invocation of this function, the user’s code should clean-up any resources allocated during the bipInitializeUserExits function. If this function is not exported, then the .lel fails to load. It is not valid to call any utility functions during invocation of bipTerminateUserExits. This function is invoked on the same thread as bipInitializeUserExits.
