INT is_ReleaseDC (HIDS hCam, HDC hDC)
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This function is obsolete and should not be used anymore.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 ).
In DirectDraw BackBuffer mode, is_ReleaseDC() releases the device context handle of the overlay buffer. If
overlay display is enabled using the is_ShowDDOverlay() function, the contents of the overlay buffer will be
updated on the screen after the handle release.
