If read() fails without EAGAIN/EINTR, the device is very likely dead. However, we must not remove the device as it might be muted/revoked. So we simply remove the event-source to avoid polling the device and simply wait for the udev-remove signal now. Note that we cannot call evdev_device_destroy() as the caller created the FD and might need custom code to close it (like weston_launcher_close()).
Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for buiding weston and its dependencies.
