I think ctypes is ok for its niche: easy interfacing with C stuff from straight Python code, without further dependencies. There will always (and necessarily) be a call overhead involved. Anyone who needs to care about per-call performance would use something else anyway (do I need to mention Cython here?) Stefan -- http://mail.python.org/mailman/listinfo/python-list
