Python Twisted example with file descriptors

I want to use twisted to control communication through Linux channels (os.pipe ()) and fifos (os.mkfifo ()) between the main process and a set of slave processes. Although I'm sure you can use twisted ones for these types of file descriptors (after all, twisted ones are great for tcp sockets that * nix abstract in as file descriptors), I can't find any examples of this use. Does anyone have any links, code examples, or tips?

It has nothing built in for asynchronous I / O. Someone wrote a libaio wrapper for him , but he was not touched for a long time, and I have no idea if he still works.

In the worst case scenario, you can use selectto see if there is anything readable, but that will not help you write.
