Syntax

INT is_UpdateDisplay (HIDS hCam)

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This function is obsolete and should not be used anymore.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

Using is_UpdateDisplay(), you can manually update the screen output in the DirectDraw modes. In normal operation, the driver performs updates automatically. There may be cases, however, where a manual update of the screen output is necessary.

Input Parameters

hCam

Camera handle

Return Values

IS_SUCCESS

Function executed successfully

IS_NO_SUCCESS

General error message

Recommended Alternative

is_DirectRenderer()
