IWMEREG — Registering a WLM Enclave

The IWMEREG service allows the caller to register an enclave in order to prevent it from being deleted. This is useful if the caller wants to schedule SRBs or join tasks to an enclave that is owned by another subsystem. Registration guarantees that the enclave will continue to exist until the corresponding deregistration is done, even if the other subsystem deletes the enclave. The system defers the enclave's deletion until after the last deregistration.

The address space identified as the home address space at the time of registration is held responsible for deregistration in case of abnormal termination of the job step, the job, or the address space itself.

The caller can run in task or SRB mode.
