Syntax
INT is_ReleaseDC (HIDS hCam, HDC hDC)
Description
This function is obsolete and should not be used anymore.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.
