Q: The C idea of (pv != NULL) is said most directly in Python ctypes how? A: We are of course supposed to write something like:
def c_not_null(pv): return (ctypes.cast(pv, ctypes.c_void_p).value != None) Yes? Working from the doc, me the clueless newbie, I was slow to guess such relevant truths as: ctypes.c_void_p(0).value == None ctypes.c_void_p(0) != ctypes.c_void_p(0) Curiously yours, thanks in advance, Pat LaVarre -- http://mail.python.org/mailman/listinfo/python-list
