This information contains
reference material for the Java request monitoring, C ECI and C EPI
user exits.
For information about installing and using the exits, see CICS Transaction Gateway: Programming Guide.
The C exit routines are described under the following headings:
- Purpose—describes the kind of processing that the exit is intended
to perform.
- When called—describes where in ECI or EPI processing the exit is
called.
- Parameters—describes the parameters supplied to the exit. Parameters
are classified as follows:
- Input—the exit may look at it, but must not change it.
- Output—the exit must not look at it, but must store a value in it.
- Input-output—the exit may look at it, and may store a value in it.
- Return codes—describes the possible values the exit can return
to the ECI or EPI. In each case the subsequent behavior of the ECI or EPI
is described.
