Someone may want to correct me, but from what I can see, the socket module is almost a 1:1 mapping between the socket support your C lib has, and Python. Plus some compatibility code for Windows. You should be able to do everything you can do in C. Your code may become Linux-specific if you're not careful, though. /Jorgen -- // Jorgen Grahn <jgrahn@ Ph'nglui mglw'nafh Cthulhu \X/ algonet.se> R'lyeh wgah'nagl fhtagn! -- http://mail.python.org/mailman/listinfo/python-list
