Usage notes

This service is only intended for use by the MVS™ BCP.
The CREI user type must be local (that is, 1).
IRRSMI00 builds the IISP in the output_ISP area and the output_IPCP areas provided by the caller. The caller must save the IISP as part of the attributes for the key.
The IPCP ALET and address are retrieved from the parameters and set into the output_ISP by RACF®.
The effective z/OS UNIX user identifier (UID) and z/OS UNIX group identifier (GID) are retrieved from the USP and set into the owner and creator fields of the output_IPCP by RACF.
The mode is retrieved from the parameters and set into the output_IPCP by RACF.
The IPC Key and IPC ID are retrieved from the CREI and set into the output_ISP by RACF.
An audit record is optionally written, depending on the audit options in effect for the system.
This service uses task-level support when z/OS UNIX has indicated in the task's ACEE that this is a task-level process.
If the SECLABEL class is active, the security label from the creating process will be propagated to the ISP. If the creating process has no security label and MLIPCOBJ is active, the request will fail with an authorization failure.
