make logfile out of cout

[pompom]

hello all!

i have to make a project for school , making a newsserver and a client.
the thing is, i send messages between them to let the user know if everything is running ok. just some simple http messages as 201, etc.

as a extention id like to build in a log file maker.
what i want is: everything that is put on the output stream will also appear in a logfile.

i already found this:

 ofstream out("logFile.txt");
  if(out) {
    streambuf *pStreambuf = cout.rdbuf();   // save cout streambuf
    cout.rdbuf(out.rdbuf());                // give cout file's streambuf
 
    // The following text will be written to LogFile.txt.  You might
    // want to do something like this to give a user the option of
    // seeing output on-screen, or getting it off-line in a file.
 
    cout << "\n  This output text will be displayed on cout, "
         << "\n  then redirected to a log file using streambufs."
         << "\n  Note that all output is written to cout."
         << "\n  Redirection occurs by giving cout the streambuf"
         << "\n  of the log file\n\n";
 
 
 
    cout.rdbuf(pStreambuf);                 // restore cout streambuf
    out.close();
 
 

this is what i want, except for the fact that i dont see anything in the terminal then. everything is outputted in the file.
I want it to appear on the user's screen as well as written in the file.

is there a way so i can simply specify that whats on cout should be coppied into this logfile? and so i dont have to add to each std::cout i have now:
ofstream file("logfile");
file << INPUTTEXT;

Thank you all for reading!

You can associate cout with a file if you want, but then it doesn't write to the monitor. The easiest way to do this is to write a function that takes the desired output as a parameter, most likely in string form, then outputs to the file and stdout.

Thank you, that did the trick like i wanted :-)
