[Pythonmac-SIG] Restrictions on what you can do in a Python module?

[Robb Brown]

I'm trying to write wrappers for dcmtk (a toolkit for the medical 
imaging DICOM standard).  At the moment I have three functions, to open 
an association (basically a network connection), close it, and send an 
echo request (like a ping).  A test program written entirely in C works 
fine but when compiled as a module and called from Python I get an 
illegal instruction when the dcmtk function to actually open the 
association is called.  I believe this function is simply opening a 
socket, connecting to a server and negotiating what flavour of the 
protocol to use.

Are there things that simply can't be done in a Python module?  What 
exactly is an illegal instruction?

Thanks for any help,

Robb
