Syntax
INT is_UnlockDDOverlayMem (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This function is obsolete and should not be used anymore.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 ).
Using is_UnlockDDOverlayMem(), you can unlock the overlay buffer in DirectDraw BackBuffer
mode. This results in an overlay buffer refresh on the screen, provided that the overlay display was
enabled using is_ShowDDOverlay() .
