The ioctls return the number of bytes copied into the destination, so just copy them into the device state instead of individually flipping bits. For easier review: rc is the return value of the EVIOCG* ioctl, which is the number of bytes copied. state variables must be initialized to 0 now, in case the kernel's FOO_MAX is smaller than libevdev's FOO_MAX. If not initialized to 0, the bytes between the two max values is undefined and we may end up generating bogus events.

libevdev - wrapper library for evdev input devices
libevdev is a wrapper library for evdev devices. it moves the common tasks when dealing with evdev devices into a library and provides a library interface to the callers, thus avoiding erroneous ioctls, etc.
git://git.freedesktop.org/git/libevdev http://cgit.freedesktop.org/libevdev/
libevdev is currently in early stages of development. Use at your own risk
The eventual goal is that libevdev wraps all ioctls available to evdev devices, thus making direct access unnecessary.
