I have a simple program that creates a thread, loops twenty times and then makes a call to close itself and perform the necessary cleanup.

When I debug the program it reaches the ExitThread(); method and pauses, ignoring the printf(); I have set up after it to signal to me it's closed.

Is this normal or am I forgetting to do something? I'm new to threading using C.

Main()

void main()
{
    Time t;
    int i = 0;

    StartTimer();

    for(i = 0; i < 20; i++)
    {
        t = GetTime();
        printf("%d.%.3d\n", t.seconds, t.milliseconds);
        Sleep(100);
    }
    StopTimer();
}

Thread Creation

void StartTimer()
{
    DWORD threadId;
seconds = 0;
milliseconds = 0;

// Create child thread
hThread = CreateThread(
    NULL,       // lpThreadAttributes (default)
    0,          // dwStackSize (default)
    ThreadFunc, // lpStartAddress
    NULL,       // lpParameter
    0,          // dwCreationFlags
    &threadId   // lpThreadId (returned by function)
    );

// Check child thread was created successfully
if(hThread == NULL)
{
    printf("Error creating thread\n");
}
}

Thread Close

void StopTimer()
{
    DWORD exitCode;

    if(GetExitCodeThread(hThread,&exitCode) != 0)
    {
        ExitThread(exitCode);   
        printf("Thread closed");

        if(CloseHandle(hThread))
        {
            printf("Handle closed");
        }
    }
}
