we can start application on Landscape or Portrait mode, and switch the mode dynamically.For some device, if app doesn't switch orientation by some menu, user can't do that, like N81, we say it only support one orientation. However, for N95/N93,user can switch orientation by the device itself, we'll say the device support two screen orientation. Can app tell one or two orientation is supported by device during application start?

I tried CWsScreenDevice::NumScreenModes(), it is not related to my question.
