SimConnect_RequestResponseTimes

The SimConnect_RequestResponseTimes function is used to provide some data on the performance of the client-server connection.

Syntax

HRESULT SimConnect_RequestResponseTimes(
    HANDLE  hSimConnect,
    DWORD  nCount,
    float*  fElapsedSeconds
    );

Parameters

Parameter	Description	Type
hSimConnect	Handle to a SimConnect object.	Integer
nCount	Integer containing the number of elements in the array of floats. This should be set to five for the full range of timings, but can be less if only the first few are of interest. There is no point creating an array of greater than five floats.	Integer
fElapsedSeconds	An array of nCount floats, containing the times. The five elements will contain the following: 0 - total round trip time 1 - time from the request till the packet is sent 2 - time from the request till the packet is received by the server 3 - time from the request till the response is made by the server 4 - time from the server response to the client receives the packet.	Array

      ....
while( quit == 0 )
    {
    hr = SimConnect_CallDispatch(hSimConnect, MyDispatchProc, NULL);
    Sleep(0);
    if (fTesting)
        {
        fTesting = false;
        float fElapsedSeconds[5];
        hr = SimConnect_RequestResponseTimes(hSimConnect, 5, &fElapsedSeconds[0]);
          ....
        }
    }
