Hello,

I have been playing around with the class fstream in the g++ library.  I
am trying to understand its intended usage and how best to use it.
I was unable to find any documentation about it.  

The open method returns a void.  What is the best way to test if the open
operation was a success.  So far, I have only been able to successfully
use the filedesc() method, to test if it is not -1.  Is there any other
way?

I am trying to create a derived stream class that can be assigned freely
to cout,cin and cerr, and to read and write to files.  So far, fstream
is the only "base" class I can use from the g++ library.  However,
I have not been able to get it to work (see my bug report post on
gnu.g++.lib.bug).

Thanks for any help.....

Jason
