Hello, I have a C library I've written an extension wrapper around that manages connections to an external server for me. When I create a connection through this library, I get a file descriptor back that I need to monitor for activity. I've been poking through the twisted code to see how I can add these file descriptors to the reactor, but I'm just not seeing how it can be done. My closest guess right now would be to wrap my file descriptor in a FileDescriptor object, but I'm not seeing how to add that to the reactor, or how to tell it what code to call when there is activity on that descriptor. Can anyone give me some insight into what I need to do, or point me at some documentation that would explain what I need to do? For system details, I'll be doing this with Python 2.3.5, Twisted 2.0.1, on both Mac OS X Tiger, and Red Hat Linux.
