- 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
