Hi!!
No, because I did a lot of changes these days... for example, now I'm trying to do with pipes, but I can describe.

I create a struct, and then I shared with shared memory, struct was this:

Code:
typedef struct _clients{
        char login[7];
        int fd;
        int stat;
}clients[3];

And struct and shared memory works good (tested).

My server is listening connections, when connection arrives then forks and the client go to child. Before fork, I saved value of "fd_client = accept(sock,0,0);" into struct client[0]->fd=fd_client;

Then, when another children needs to write in the socket of another child, I search in the struct the fd of the another child, because I know he's login. Then I call write(fd,"test",4);

Problem? word "test" is send to the actual child, and I can see in his screen the word "test", when I need to write this "test" in the screen of the other child.

Now, seeing this, maybe I need to save value of "sock" instead "fd_client"??

Thanks
