    ostream and ofstream

    I have been designing a class and trying to come up with a better way of handling error output. If a file is specified, I want all errors to be written to the file, if no file is specified, I want the errors to be written to cerr. I have been using something like this:
    Code:
    // errfile is declared as ostream* errfile
    if (file_given) {
        errfile = new ofstream(filename);
    }
    else {
        errfile = &cerr;
    }
    Is this a valid way of handling the error output?

    Also in the class destructor, I do this:
    Code:
    if (errfile != &cerr) {
        delete static_cast<ofstream*>(errfile);
    }
    Any advice would be appreciated?

    Thanks,
    - Sean

    This thread looks at what you are trying to do.
