What is exactly a ndll ?

[Marcelo de Moraes Serpa]

I know that it's some kind of shared library (like a Windows DLL or Unix SO) but I'd like to know more about it, like how is it created, relationship between targets (neko,cpp), use-cases…; the information is scarce and spread around, and I didn't find any article that actually talks about it.

I'm not the most qualified on this subject, but an ndll is a dll with the express purpose of marshalling data between neko (and more recently haxec++) and c / c++. The neko foreign function interface is here and describes the interfaces for bi-directional communication.

It's a dynamic library.

Sometimes the extension is "ndll", but other times the extension is "dylib" or "so", depending on the platform. Technically, you can use the <ndll /> tag in NME to attach any native library to your project.

There's an interface called CFFI that handles communication between Neko or HXCPP, into native code. This is what someone might set up in an NME extension (like the "sqlite" library) or which is used in NME to handle the "glue" between NME's own native "NDLL" library and the high-level code.

Thanks guys, it makes sense now. I'll look into FFI in general in order to understand a bit more about the subject.

Now, I just found this: http://haxe.org/doc/advanced/haxewithexteralc

That's what I was looking for :)
