INT is_UnlockDDOverlayMem (HIDS hCam)

Description

hint_info

This function is obsolete and should not be used anymore. We recommend to use the is_DirectRenderer() function instead.

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().
