If you are just checking the name/password against an existing list, then you only need read. If you want to add something, then you need a different mode. However, I think you may be better off uing fopen, instead of popen, if you are trying to do what I think you are. The documentation for fopen has a comprehensive description of the modes available; note that w is kindof destructive in the wrong context :-) Cheers -- David Robley Temporary Kiwi!
