I think that is not correct.

hWnd = CreateWindow ("STATIC", "", WS_POPUP, 0, 0, 0, 0,NULL,NULL,NULL,NULL);
ShowWindow (hWnd, SW_HIDE);
wpOrigProc = (WNDPROC) SetWindowLong(hWnd, GWL_WNDPROC, (LONG) pg_WinProc);

HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam)
MSG rMsg;

rMsg.message = uMsg;
rMsg.wParam = wParam;
rMsg.lParam = lParam;

// printf ("got message %d\n", rMsg.message);
switch (rMsg.message)
