look at this
http://www.ddj.com/dept/cpp/184401518
the article is a good introduction to Boost Thread concepts
for your needs use concepts described in paragraph 1 and 2 (listing 1, 2 and

> I am not very good at C++ (I am still studying) but I was asked to setup a

> At the very beginning I thought to do it with C syntax, forking a new

> It worked, but because of the common resource, results are returned in the
> wrong way, not in the correct order.

> if( fork()==0 ){ //child process
> close(listen_sd);
> //reading from conn
> //elaborating received data, through a common resource, to be
> "mutexed"
> //sending results to conn

> //parent process
> close(conn);
