Hi there!
You posted this question as a reply to something totally unrelated, so I split it into it's own thread. Please read our
Posting Guidelines and keep to them in future (including opening a own thread, when asking a new and unrelated question). That also makes the chances bigger, that you'll get the right answer.
By the way, I'd say this is more of a C/C++ Question than a Linux/Unix question, so I'm moving this to the C/C++ Forum.
Greetings,
