Ah. In that case, I recommend to use the ioctl module; you won't need a C wrapper, then. > Although the number of control codes/structures is finite, it would make the > wrapper function fairly large. *Some* code to handle this will be very large, regardless of how you write it. > You seem to think that building the structure from python would be a > mistake: why is that ? It's very error-prone. You have to match the C structure layout of the compiler precisely, and you even have to get the alignment right, something that can't be done reliably in Python. > PS: the wrapper also has to work under multiple OSs That makes it worse: now you not only have to match the C compiler's expectation on a single processor, but on different ones. Perhaps you should be using ctypes. Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list
