Is there a way to find out if the user is in the Exposé mode? (i.e., all windows are being shown.) Thank you.

There's no public API for getting this information. What problem are you trying to solve?

I am creating a program that emulates a multi-touch trackpad. If you swipe four fingers up in the normal state, it's just like you press fn+F11 keys. If you are in the Exposé state, it's like you press the Escape key. So, I want to know if the user is in the Exposé state at a given moment or not. Thanks for your help anyway.

You don't need this information. If the user is not in Exposé, F11 (or fn-F11) will enter Exposé. If the user is already in Exposé, F11 (or fn-F11) will exit Exposé. So just send F11 (or fn-F11) unconditionally.
The real challenge is determining the correct key command to send. On a laptop or small Apple Wireless Keyboard, the command may include the fn modifier, but on a desktop machine with a full-size keyboard, the command will more probably be F11 alone. Furthermore, it's user-configurable.
The correct way to toggle Exposé programmatically is a separate question.
