How to give back hand to screen

[sylvain_nurun]

Hello everybody,

I have a little problem..

A program I'm modifying has the following behavior :

If an option is given, it will write information messages to the screen, but if an other option is given, it will write information messages to a File named LogFile.txt ...

Now, what's done in the code is this :

freopen("LogFile.txt", "a+", stdout);
To close stdout and assign LogFile.txt to the standard output.

After everything is done, I need to give back the hand to the screen to write a message about the success of the program, based on some text in an other file.

Everything I saw about the freopen function didn't talk about giving back the hand to the screen..

I use
freopen("NUL", "a+", stdout);
to close the stream stdout assigned to LogFile ( it is shared by a lot of programs called from the main one) , but I can't write anything on the screen from then on.

Does anybody know how I can write back to the screen without leaving the program ?

Thanks
Sylvain
