Syntax

INT is_ReleaseDC (HIDS hCam, HDC hDC)

Description

Achtung

This function is obsolete and should not be used anymore.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.

Input parameters

hCam	Camera handle
hDC	Device context handle returned by is_GetDC()

Return values

IS_SUCCESS	Function executed successfully
IS_NO_SUCCESS	General error message
