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 ?

I personally prefer event loop libraries such as libev[1]. They handle all the interfacing with the event mechanism the OS provides, so you only need to register a callback function. HTH, Jonathan Neuschäfer [1] http://software.schmorp.de/pkg/libev.html
