A question about IO watches. 

I am developing a Linux USB2 camera driver.
 My Gtk app opens it simply by:
camera_fd=open("/dev/video1").

Is that possible to watch this "camera_fd" in the Gtk
main loop just like what we usually do on socket or
file?  (Say, I want to register a callback that is
called after camera data is ready.)
What kind of interface the camera driver should
provide  to support that?

Thanks,
Dan
