Interprocess Communication Messages
Subject_Data. The event-exit process might return the Message_Response_Data,
depending on the type of event.
Message_Data sent by the Safeguard software has a different structure for each type
of event, as shown in Table 15-4 on page 15-18 through Table 15-6 on page 15-22.
The event-exit process replies to logon and password change events by overlaying the
Message_Data with message response data as shown in Table 15-7 on page 15-22
and Table 15-8 on page 15-23. It does not provide message response data for access
control or logon abort events.
The names of the data items in Table 15-2 on page 15-14 through Table 15-8 on
page 15-23 are pseudonames, and do not exactly match the names as specified in the
DDL. For variable names, see the DDL output. The DDL is located in the file
ZSAFEGRD.SEEPDDL.
Figure 15-2 illustrates the structure of the message buffer between the Safeguard
software and the event-exit process.
