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This function is obsolete and should not be used anymore.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