[Pharo-dev] uFFI: What is the difference between FFIExternalObject and FFIOpaqueObject?

I'm working on improving the documentation. I'd like examples of situations when you'd use one or the other and why... Also, the FFIOpaqueObject class comment could be fleshed out a bit. Check out this excerpt: "this means we always access them through a reference. Now, we could declare the pointer to the structures, but then our declarations wouldn't be as close to C as we want." What would be an example of "declar[ing] the pointer to the structures" and the resulting declarations that "wouldn't be as close to C as we want"? ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
