I would also recommend to look at Python's c-types and especially IronPython's implementation:
http://github.com/ironruby/ironruby/tree/master/Languages/IronPython/IronPython.Modules/_ctypes/ Many of the features might be similar to Ruby's FFI and it would be good to share the implementation with IronPython when possible.

I don't know whether or not P/Invoke alone can match the functionality of libffi. I'd have to look through some of libffi and see if there's anything can't be accomplished in C#. If everything can be accomplished in C#, I'd go that route. We could emit types at runtime that have the necessary DLLImport attributes and such (something I've already done for little projects of mine). -Charles On Fri, Aug 20, 2010 at 4:14 PM, Will Green <w...@hotgazpacho.org<mailto:w...@hotgazpacho.org>> wrote: Couldn't this be implemented via P/Invoke?

In fact, In my infinite laziness, I posted a job for a couple hundred bucks on Rent-A-Coder, hoping someone could essentially port JFFI to C#, so I could focus on writing the actually IronRuby library... but nothing came of that. I'm tempted to suck it up and start coding this myself. Would you be interested in working together? I figured I'd take the approach of essentially writing "NFFI", and then write an IronRuby lib around that. -Charles On Fri, Aug 20, 2010 at 2:33 PM, Ryan Riley <ryan.ri...@panesofglass.org<mailto:ryan.ri...@panesofglass.org>> wrote: I know that we've discussed this in the past, but I'm interested in doing it for two reasons: 1. We use mono with a bridge to ObjectiveC and Cocoa, and we'd like to investigate libffi via mono as a potential replacement for our current bridge. 2. I'm interested just for the sake of learning more about FFI. Mono appears to have had a libffi implementation that was later removed, so I think I have a place to start. However, I'm not sure that's the right starting point. Does anyone have a suggestion for how to get started? I've been taking a look at libffi and DllImport, but I'm not sure if those are the right directions, something else, or what.
