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 :-)
