is_ShowDDOverlay
Syntax
INT is_ShowDDOverlay (HIDS hCam)
Description
This function is obsolete and should not be used anymore.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.
