Hi,

I have to capture kernel udev events through libudev. One of API provides asynchronous events by reading on file descriptor. I found that there two ways to do that.

1) select call 2) epoll

I also found that epoll is smarter and meant to replace old select call.

What are your thoughts on these ? Which one is better ?

If you are ok to be limited to linux, I would highly recommend using epoll because of scaleability. Using select is almost like creating a new epoll descriptor for every call instead of reusing it. -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com
