INT is_ShowDDOverlay (HIDS hCam)
Description
Attention
This function is obsolete and should not be used anymore. We recommend to use the is_DirectRenderer()
function instead (see also Obsolete functions ).
In DirectDraw BackBuffer mode, is_ShowDDOverlay() displays the overlay, i.e. the most recent data stored in
the overlay buffer. With some graphics cards, overlay display may reduce the frame rate.
