Hi, > What's wrong with something like: > > module MyLib >   extend Fiddle::Importer >   dlload "mylib.so" >   FOO = 1 >   BAR = 2 >   BAZ = 3 >   extern "void func(int)" > end > > MyLib.func(MyLib::BAR) Somehow I haven't thought about using constants for the enum's values, but yes, it is an option indeed. It doesn't look as rubyish as a     MyLib.func(:bar) would do, though, but I understand that this is something I have to implement. Thank you for your suggestion anyway. > You could wrap that list of const assignments up into some sort of > class method `enum` that creates the consts from a list of names (and > maybe a starting offset). Yes, that's the obvious consequence to draw from this approach. > what you're asking for wrt fiddle treating enums like types rather > than named numbers is outside the scope of what fiddle is for.

The expectation came from using ruby-ffi, which does have special treatment for enums[1], and as ruby-ffi and fiddle serve the same purpose after all, it did not occur to me that handling of enums is out of scope for fiddle.
