Syntax
INT is_UpdateDisplay (HIDS hCam)
Description
This function is obsolete and should not be used anymore.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.

Notes on parameter validity
Functions that refer to an initialized camera have the camera handle HIDS hCam as the first
parameter. All parameters that are set using these functions remain valid for as long as the handle is
valid, that is, until you close the corresponding camera or exit the program. The next time you open
the camera, it is initialized with the defaults again.
