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This function is obsolete and should not be used anymore.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

Input parameters

hCam	Camera handle

Return values

IS_SUCCESS	Function executed successfully
IS_NO_SUCCESS	General error message
