Hi Simon, (This is also a follow-up on concerns raised by Christian on #pypy today)

The trick would be to have two implementations of the lltypesystem objects (array, structures, etc.). The existing implementation would only be used when ctypes is not available; if ctypes can be imported, then the other implementation could systematically be used. With a bit of effort it could have a fully compatible interface, but be internally implemented as ctypes objects (e.g. lltype.malloc(S) would build a ctypes structure type corresponding to S, and internally instantiate that). Then we could really call rffi functions, by turning it internally into a ctypes function and calling it with the ctypes objects underlying the passed-in arguments. This might even not be completely insane - in my opinion, less than implementing and maintaining rctypes itself. It's also something that can be done by someone not deeply into the code base, as long as he knows the lltype interface and how to use ctypes. A bientot, Armin. _______________________________________________ [email protected] http://codespeak.net/mailman/listinfo/pypy-dev
