##### Remarks

This function should be used in conjunction with returned structures of type [SIMCONNECT\_RECV\_EXCEPTION](../structures-and-enumerations/simconnect-recv-exception/) to help pinpoint errors (exceptions) returned by the server. This is done by matching the send ID returned with the exception, with the number returned by this function and stored appropriately. This function is primarily intended to be used while debugging and testing the client application, rather than in a final retail build.
