INT is_ShowDDOverlay (HIDS hCam)

Description

Achtung

This function is obsolete and should not be used anymore.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.

Camera handle
