Cannot Issue Second Allocate from a CPI-C Application (157442)


The information in this article applies to:

  • Microsoft SNA Server 2.11 SP1, when used with:
    • the operating system: Microsoft Windows NT
This article was previously published under Q157442

SYMPTOMS

CPIC reports CM_PRODUCT_SPECIFIC_ERROR (20) when you try to issue an MC_ALLOCATE after you issue a RECEIVE_ALLOCATE and receive a TP_ID. An APPC trace will reveal a primary and secondary error codes indicating that the TP_ID is incorrect. The following event will be registered in the Application Log:
Event 3028: Error returned from APPC that does not map to CPI-C error,
00000100

CAUSE

The CPIC library was not handling APPC TP_IDs correctly if an application issues a Receive, cmrcv(), and then issues an Allocate, cmallc().

STATUS
