30 * of calls to this function.
31 * Parameters: LPCTSTR lpszDeviceName specifies the display device
32 * DWORD iModeNum specifies the graphics mode
33 * LPDEVMODE lpDevMode points to structure to receive settings
34 * Variables :
35 * Result : If the function succeeds, the return value is TRUE.
36 * If the function fails, the return value is FALSE.
