Re: [email] RE: Restarting game exe

Haven't tried this, but I'm sure there's a way to spin on the previous
HINSTANCE that is passed in on WinMain - that is, if you are worried about
dual execution.

Something like
if (hPrevInstance != NULL)
{
    // Can't remember what to use to get the module handle.
    // You may be able to just straight up do
    WaitForSingleObject(hPrevInstance, 100 /*timeout in case the other
doesn't exit*/ );

    // But that doesn't feel right. (be sure to check for timeout, in case
the
    // user actually executed it twice
}

Something like that. There's probably a few steps to get the correct handle
to Wait() on.
