<tteras> old kernels have only eventfd() <tteras> they noticed uh oh, we need add a new parameter <tteras> so there's eventfd2() syscall <tteras> when it was added to glibc <tteras> eventfd2 was already there <tteras> so the glibc call got name eventfd() even though it had signature of syscall eventfd2() <ncopa> so they picked eventfd() <tteras> yeah <ncopa> doh Requires 2.6.27+ kernel. The old eventfd() syscall, is not really usable and emulation is not feasible.
