TPEnded

Terminates access to LU 6.2 API and releases resources.

Syntax

 I16V   I32       
TPEnded(TPID, Status);

Parameters

TPID: Required; 16-bit signed integer by value; input. This number is assigned to the specific instance of the TP during the execution of the TPStarted intrinsic. (More than one instance of the same TP may be executing at once, and the TPID uniquely identifies a single instance of a TP.)
Status: Required; 32-bit signed integer; output. Indicates the result of intrinsic execution. See the "Status Parameter" section, earlier in this chapter, for more information.

Description

The TPEnded intrinsic is used to release all resources allocated for the execution of this TP. If the TPStarted intrinsic has been called within a TP, the TPEnded intrinsic should be called before the TP finishes executing.

If a TP terminates abnormally, and TPEnded cannot execute successfully, LU 6.2 API will attempt to release the resources allocated for the TP.




	NOTE: Always call `TPEnded` to end your TPs. If all conversations have been deallocated, the TP is still executing, and `TPEnded` has not been called, the node manager cannot bring down the APPC subsystem without first aborting the TP. Call `TPEnded` as soon as all conversations have been deallocated.

Status Info Values

 0     Successful Completion.
-1     Intrinsic called with parameter out of bounds.
-15    Invalid 'TPID' parameter specified in intrinsic call.
-19    APPC subsystem is inactive.
-20    Not enough stack space for intrinsic to run.
-90    An internal error in Presentation Services has occurred.
-1002  An internal error at the mapped conversation level has occurred.
-1003  Required parameter missing.
-1040  Conversation(s) not deallocated before calling TPEnded.
