Figure 1 illustrates the parameter structure
for the ACS installation exits. A
4 KB work area exists on a doubleword boundary for each ACS installation exit. You
can use this work area to satisfy the reentrant requirement. The following
macros map the parameters that are passed to each ACS installation exit:
- IGDACERO
- Maps the read-only variables that the ACS exit can reference when
selecting an SMS class.
- IGDACERW
- Maps the read-write variables that the ACS exit can set when selecting
an SMS class.
- IGDACSPM
- Describes the parameter list for an ACS installation exit.
