    Hi Marc, hi All,

    I did not read anything in my OpenSUSE distribution documentation related 
to buffering and "line" buffering. But I found on Internet.

    Thank you very much. The simplest way seems to be a simple "setbuf(stdout, 
NULL);" ! I wrote a helping function using vprintf. This sould work a better 
way.

    So, the reason why the program stopped has nothing to see with fflush() ! 
Aïe, aïe, aïe!

    Sincerly,
Patrick
