is_UpdateDisplay

USB 2.0

GigE

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This function is obsolete and should not be used anymore.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
