Well, if you think about it, this is what Gambit does internally - in a sexp the symbol abcde is wrapped internally to (string->symbol "abcde"). In the C world, you could make a string->symbol wrapper so you'd get ___SCMOBJ alex_sy1 = string_to_symbol("alex_sy1"); etc. With some C macro magic, perhaps that could even be written as define_scheme_sy(alex_sy1) or something. (Also, have a look at string->symbol's definition, imaginably a lot of it is written in C in such a way that you could just call it directly from C, well, that might more probably not be an option too.) 2013/2/19 Alex Young <alex@blackkettle.org>
2) you're returning symbols so I think you want your C function to return to Scheme. Have your C function return a result code and wrap it in a Scheme procedure that maps the result code onto a symbol. You can look at Gamsock on the dumping ground for examples of how to wrap a low-level C function in a Scheme procedure that handles the Scheme objects.
Yeah, I was trying to avoid having to do this. I'd be defining the return codes twice - once as ints (or whatever) and once as symbols. I guess that's all macroable away, but still... not particularly elegant.
Thanks for the suggestions :-)
