Well, I think I’ve made a little progress - hoping to attach a simple function soon. I am concerned about one thing though - we need to be able to call function pointers, but I think that _Marshal.GetDelegateForFunctionPointer_ only supports the STD calling convention. Any thoughts on how we might support cdecl? Presently, it’s not a blocking concern - so I’ll cross that bridge when the time comes… Wayne: Sorry - I meant to send that to the mailing list, as opposed to sending it directly to you. -Charles ---

Well, with some really, \*really \*ugly hacking, I’ve managed to get this far (the first example from FFI wiki): irb(main):011:0\> module Hello irb(main):012:1\> extend FFI::Library irb(main):013:1\> ffi\_lib FFI::Library::LIBC irb(main):014:1\> attach\_function ‘puts’, [:string], :int irb(main):015:1\> end _(Object doesn’t support #inspect)_ =\> irb(main):016:0\> Hello.puts(“Hello, World”) Hello, World =\> 0 (dunno why that _“(Object doesn’t support #inspect)”_ shows up…) Anywho, I think we might might have a significant portion of FFI implemented fairly soon. The codebase is still pretty unstable/crappy, but I’m hoping to get it ready for contributions soon. -Charles On Sun, Mar 27, 2011 at 6:28 PM, Charles S. \< ---

I overlooked the UnmanagedFunctionPointerAttribute[http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.unmanagedfunctionpointerattribute.aspx](http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.unmanagedfunctionpointerattribute.aspx) . -Charles On Thu, Mar 31, 2011 at 4:41 AM, Charles S. \< ---

Ryan, I’m _absolutely_ interested, but, as much as it shames me to say, the [ALT.NET](http://ALT.NET) Seattle conference wasn’t on my radar until just now. I’m down for next year though, especially if you plan to give an F# workshop. -Charles ---

Are you coming to [ALT.NET](http://ALT.NET) Seattle? We have an OSS track this year to help people learn how to contribute to projects. Interested? Ryan Sent from my iPhone ---

All, IronRuby FFI is coming along well. So far, I support most of the FFI::Function uses, including attaching to function pointers, library functions, and wrapping Procs. Structs are at 50%, and callbacks need to be implemented. I’ll need just another week or two to cut the first release. -Charles On Thu, Mar 31, 2011 at 5:00 AM, Charles S. \< ---

That’s a possibility, but it might have to come further down the road. -Charles ---

I just wanted to check how the Ruby FFI library was coming along?
