"symbols" including functions (of all prototypes( and variables. Whilst casting any function type to another violates ANSI C (I believe), it is a necessary evil in shared-library APIs. However, it is quite conceivable that functions in general and data symbols could very well be represented differently to each other on some systems, as Bodo said; > Since the function/object distinction is a lot more likely to be > important on real-life platforms supporting DSO *and* it can be quite > easily done *and* it will silence compilers that don't like > assignments from void pointers to function pointer variables, why > not do it? I agree. So this change splits the "dso_bind" handler in DSO_METHOD into "dso_bind_var" and "dso_bind_func". Similarly the exported function DSO_bind() has been split in two. I've also put together changes for the various DSO_METHOD implementations, but so far only DSO_dlfcn() has been tested. BTW: The prototype for dso_bind had been a bit strange so I've taken the opportunity to change its shape (in both variations). Also, the README has been updated - particularly with a note about using customised native name-translation for shared libraries (and that you can't do it yet).
