Two main goals of this library: - 'transparently' handle SYN_DROPPED events - avoid errors in ioctl handling by providing a simpler interface. Keeps a cached copy of the device for quick querying. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

libevemu - wrapper library for evdev input devices
libevdevdev 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.

libevdev is currently in early stages of development. Use at your own risk
Device capabilities
libevdev provides interfaces to query a device's capabilities. These interfaces are type-safe (as opposed to the ioctl bits) and protect against invalid codes, etc.
SYN_DROPPED handling
SYN_DROPPED is sent by the kernel if userspace cannot keep up with the reporting rate of the device. Once the kernel's buffer is full, it will issue a SYN_DROPPED event signalling dropped event. The userspace process must re-sync the device.
libevdevdev semi-transparently handles SYN_DROPPED events, providing an interface to the caller to sync up device state without having to manually compare bitfields. Instead, libevdev sends the 'missing' events to the caller, allowing it to use the same event processing paths as it would otherwise.
Changing devices
libevdev provides interfaces to modify the kernel device.
