You could post termination message to the IO completion port using PostQueuedCompletionStatus API call or simply close IOCP handle using CloseHandle.

If a call to GetQueuedCompletionStatus fails because the completion port handle associated with it is closed while the call is outstanding, the function returns FALSE, *lpOverlapped will be NULL, and GetLastError will return ERROR_ABANDONED_WAIT_0.
