APS_CAPDATA_REQ_
APS Procedure Calls
3–56 056783 Tandem Computers Incorporated
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.
acse-release-reason input
INT:value
indicates why the release for an ACSE connection is being accepted or rejected.
This parameter applies only to ACSE and is optional; it is ignored in X.410-1984
mode. For the possible values of this parameter, see ZAPS-VAL-RLS-RSN-xxx in
Appendix A. The default value is ZAPS-VAL-RLS-RSN-NOVALUE.
Consideration
The maximum amount of user data you can send with this primitive depends on the
layer of your connection, whether you are using session version 1 or session version 2,
and (for presentation and ACSE connections) whether your connection is in normal
mode or X.410-1984 mode. The maximum length of the user-data parameter is as
follows:
Session version 1 Session version 2
Session connection 512 bytes 10240 bytes
Presentation connection (normal mode) < 512 bytes < 10240 bytes
ACSE connection (normal mode) < 512 bytes < 10240 bytes
For a normal-mode presentation or ACSE connection, you can send as much data as
will fit in a 512-byte PPDU (for session version 1) or a 10240-byte PPDU (for session
version 2); the maximum length depends on the encoding.
For a presentation or ACSE connection in X.410-1984 mode, the maximum amount of
data is the same as that for a session connection.
