Application Verifier break message

Use of an invalid Winsock extension function pointer detected

Probable cause

Microsoft Winsock Extension functions are callable only by querying Winsock for the function pointer value at runtime. The Winsock runtime has been unloaded since this function pointer was returned. The caller likely kept a copy of the function pointer after calling WSACleanup and tried to reuse it.

Troubleshooting steps

Enter k to find the caller that used a Winsock function pointer after Winsock had been unloaded.

Enter dps Parameter 1 to see the call stack when this function pointer was returned.

Enter dps Parameter 2 to see the call stack when Winsock was unloaded, invalidating this function pointer.

Information displayed by Application Verifier

Parameter 1 - Last call to get a Winsock function pointer

Parameter 2 - Last call that unloaded Winsock, invalidating the function pointers

Parameter 3 - Not Used

Parameter 4 - Not Used
