RE: [GD-Windows] Finding HWND of the current thread

Useful functions:
	EnumThreadWindows
	GetConsoleWindow

And for a brute force window search:
	GetWindowThreadProcessId

Subject: [GD-Windows] Finding HWND of the current thread

For my simple audio library I'm stuck doing something a little gross,=20
and that's passing an HWND to the library upon initialization, only=20
because IDirectSound::SetCooperativeLevel() needs an HWND.

Now, you CAN use GetDesktopWindow() and NULL, but that's not the=20
correct way and there are supposedly some failure cases when you use=20
those (e.g. multiple instances using GetDesktopWindow()), and God=20
knows what the HWND is really used for in DirectSound and what can=20
happen if you do something like create a hidden window and bind DS to=20
that instead of to your real application window.

Anyway, that aside, instead of passing in HWND, I was thinking it=20
might be possible to find the window of the current thread by=20
enumerating all windows in the system and comparing their owner=20
threads with the current thread and using that.

Is there anything glaringly wrong with that, other than the potential=20
situation that there is none (e.g. console application) and having to=20
fallback at that point.
