Registration Facility APIs

The registration facility APIs provide the capability to:

• Register and deregister exit points with the registration facility.
• Add and remove exit programs to and from the registration facility repository.
• Retrieve exit point and exit program information from the repository.
• Designate the order in which exit programs are called.

Before using the registration facility APIs and registration facility preprocessing exit program, read Using Registration Facility APIs and Registration Facility Preprocessing Exit Programs.

The registration facility APIs are:

• Add Exit Program (QUSADDEP, QusAddExitProgram) adds an exit program entry to a specific exit point or replaces an existing exit program.
• Deregister Exit Point (QUSDRGPT, QusDeregisterExitPoint) removes an exit point and all associated exit programs from the registration facility.
• Register Exit Point (QUSRGPT, QusRegisterExitPoint) registers an exit point with the registration facility or updates an exit point.
• Remove Exit Program (QUSRMVEP, QusRemoveExitProgram) removes an exit program entry from a specific exit point.
• Retrieve Exit Information (QUSRTVEI, QusRetrieveExitInformation) retrieves information about one or more exit points and exit programs.

The registration facility preprocessing exit programs are:

• Preprocessing for Add Exit Program for Registration Facility allows for processing to take place before an exit program is added to an exit point.
• Preprocessing for Remove Exit Program for Registration Facility allows for processing to take place before an exit program is removed from an exit point.
• Preprocessing for Retrieve Exit Program for Registration Facility allows for the exit point provider to store the exit program information.
