APPC Application Unable to Cancel TEST_RTS_AND_POST

Article ID: 172800

Article Last Modified on 6/24/2004



APPLIES TO

  • Microsoft SNA Server 3.0 Service Pack 4
  • Microsoft SNA Server 4.0



This article was previously published under Q172800


SYMPTOMS

If an APPC application calls TEST_RTS_AND_POST and requests asynchronous completion, and later attempts to cancel the call using WinAPPCCancelAsyncRequest, the request is not cancelled.

If SNA Application APPC API tracing is enabled, the trace will indicate two completion events for the TEST_RTS_AND_POST function: one immediately after the call is made, and a second return when the TEST_RTS_AND_POST finally completes. The cancel request appears to have no effect.

CAUSE

The APPC interface is not properly canceling the TEST_RTS_AND_POST.

STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 3.0 and 3.0 Service Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack.
