APS_ACTIVITY_INTERRUPTREQ_
his procedure allows you to abnormally terminate the current activity, but without
canceling work completed before the interruption. Note that an interrupt request may
cause undelivered data to be lost. You can issue an activity interrupt request only if an
activity is in progress and you hold the major/activity token.
To resume work on an activity after suspending it, call
APS_ACTIVITY_RESUMEREQ_.
status := APS_ACTIVITY_INTERRUPTREQ_
( cepi ! I
,[ activity-reason ] ! I
,[ tag ] ! I
,[ user-data ] ); ! I
status returned value
INT
indicates the outcome of the call. For the possible values of ZAPS-VAL-STATUS-
xxx, see “Status Codes” in Appendix B.
cepi input
INT:value
is the connection endpoint identifier (CEPI) for this connection.
activity-reason input
INT:value
is the reason for your interrupt request. All values of ZAPS-VAL-ACT-xxx are
allowed; see Appendix A for the possible values.
tag input
INT(32):value
is for use in nowait mode only. Specify a unique value to identify this instance of

correct instance of the procedure call.
