I tried the cfuntype and proto steps, and it's not crashing now (that's good), but now i'm just left with null pointers as a return object. I'm still working through all of the examples you sent. They were extremely helpful. Here's where I'm at now... What is strange is I can actually get smiGetNode to work if I don't cfunctype/proto it. If i do, nada. however, the smiGetNextNode fails no matter what, usually with a segfault, but depending on how i construct it, sometimes a null pointer. constants.py: http://pastebin.com/f3b4Wbf0 libsmi.py: http://pastebin.com/XgtpG6gr smi.c (the actual function): http://pastebin.com/Pu2vabWM -- http://mail.python.org/mailman/listinfo/python-list
