Registration Facility Using ILE APIs—Examples
Following are the entire program listings for the ILE C programs discussed in the
preceding topics. The programs perform the following tasks:
Register an exit point and add an exit program
Retrieve exit point and exit program information
Remove an exit program and deregister an exit point
These example programs are also shown in additional languages in “Integrated
Language Environment (ILE) APIs—Examples” on page B-47.
Register Exit Point and Add Exit Program—ILE C Example
The following program registers an exit point with the registration facility and adds
an exit program to the exit point.
