I want to contribute a couple of points: void* is not really great even for C because of type safety. The compiler cannot check that when you request a double you don't pass a pointer to an int. Even if you go with void* for C, you still aren't tied to any approach for other languages. For example, for dynamic languages a function that returns a value (instead of passing a variable by reference) would better fit into their programming paradigm. You can: 1. Create wrapper functions for each gettable variable. 2. Create a single wrapper function for all gettable values of a single type. Each function will take an enum member and return a value of some type. Structs do map to other languages (unlike void*). But other problems arise instead. For example, think about Perl. Is it Perl-ish to pass a reference to a hash and get a single value into it? I don't think so. This is just an example, but I guess that same reasoning applies to other languages.
