This is the caller's responsibility, for two reasons: * we don't know if O_NONBLOCK is set, so draining the fd isn't a simple matter of read() until EAGAIN. A select() + read() could work around this of course. * for stateless information, keys and relative data, it is not a problem when there are events waiting on the fd already, they are processed correctly, albeit with a delay. So punt this decision to the caller, they openend the fd, they know if they care about delayed events, they can drain the fd before handing it to us.

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/
The eventual goal is that libevdev wraps all ioctls available to evdev devices, thus making direct access unnecessary.
