APS_SYNC_MINORREQ_ This procedure allows you to define a minor synchronization point. As a result of
your call, the service provider calculates a new synchronization point serial number
and notifies the remote application of the new synchronization point.
You can issue this primitive only if all of the following conditions are true:
You hold the synchronize-minor token.
An activity is in progress, if activity services are available on the connection.
You hold the data token, if it is available on the connection.
This procedure also allows you, optionally, to use basic concatenation to send a token
give request primitive along with the synchronize minor request primitive.
status := APS_SYNC_MINORREQ_ ( cepi ! I
, minsync-ack ! I
,[ user-data ] ! I
,[ tag ] ! I
,[ give-tokens ] ); ! 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.
minsync-ack input
INT:value:(ZAPS-DDL-BOOLEAN)
specifies whether or not you are requesting an explicit acknowledgment from the
remote user. The following values are possible for this parameter:
ZAPS-VAL-FALSE You are not requesting an acknowledgment.
ZAPS-VAL-TRUE You are requesting an acknowledgment.
user-data input
INT .EXT:ref:*
contains the user data you wish to send to the remote application; see
“Considerations” for the maximum amount of data you can send. You must
define the structure of the data buffer, as described under “Defining User Data
Buffers” in Section 2. For a normal-mode presentation or ACSE connection, you
