C++ Module DLL Freeze P3D

[John doe]

Hi,

I'm trying to figure out how I can run my module .DLL to do some calculation without freezing the main P3D.exe process.

Here's a sample of what I tried (I'm using the Cabin Confort Sample of the SDK and trying to add a method that will attempt to connect to a Pipe. The method is pipeInit(). I'm currently simply trying to make P3D continue working while the pipeInit is waiting and retrying to connect to the Pipe Server (which is not running for now).

void FSAPI  module_init(void)

{

    if (NULL != Panels)

    {

        ImportTable.PANELSentry.fnptr = (PPANELS)Panels;

        CABINPanelCallbackInit();

        std::thread t1(pipeInit); // I try to load as a seperate thread since the method is trying to connect every 1500ms and would freeze P3D.

    }

}

Here's the pipeInit()

void pipeInit()
{
    //Pipe Init Data
    char buf[100];

    lpszPipename1 = TEXT("\\\\.\\pipe\\toMyOtherApp");
    lpszPipename2 = TEXT("\\\\.\\pipe\\fromMyOtherApp");

    DWORD cbWritten;
    DWORD dwBytesToWrite = (DWORD)strlen(buf);

    //Thread Init Data
    DWORD threadId;
    HANDLE hThread = NULL;

    BOOL Write_St = TRUE;

    Finished = FALSE;
    isPipeConnected = FALSE;

    printf("C++ DLL running in Sim\n");

    while ((hPipeTo == NULL || hPipeTo == INVALID_HANDLE_VALUE) || (hPipeFrom == NULL || hPipeFrom == INVALID_HANDLE_VALUE))
    {
        hPipeTo = CreateFile(lpszPipename1, GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, NULL);
        hPipeFrom = CreateFile(lpszPipename2, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, NULL);

        if ((hPipeTo == NULL || hPipeTo == INVALID_HANDLE_VALUE) || (hPipeFrom == NULL || hPipeFrom == INVALID_HANDLE_VALUE))
        {
            printf("Could not open the pipe  - (error %d)\n", GetLastError());
            Sleep(1500);
        }
        else
        {
            isPipeConnected = TRUE;
        }
    }
    
    // Do something here after pipe connected
}
