056783 Tandem Computers Incorporated 3–61
APS_CONTROL_GIVEREQ_ This procedure allows you to request the service provider to give all available tokens
to the remote application. You can issue this primitive only if both of the following
conditions are true:
Activity services are available on the connection, but no activity is in progress.
You hold the major/activity token and all other tokens that are available on the
connection.
status := APS_CONTROL_GIVEREQ_ ( cepi ! 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.
tag input
INT(32):value
is for use in nowait mode only. Specify a unique value to identify this instance of
the procedure call. When the operation is complete, the MFM_AWAITIOX_
procedure returns the tag value, allowing you to match the completion with the
correct instance of the procedure call.
user-data input
INT .EXT:ref:*
for session version 2 only, contains the user data you wish to send to the remote
application; see “Consideration” for the maximum amount of data you can send.
You must define the structure of the data buffer, as described in “Defining User
Data Buffers” in Section 2. For a normal-mode presentation or ACSE connection,
you must also encode the data, as described in “Encoding ACSE and Presentation
User Data” in Section 2.
