[newb] how to use threads with sockets ?

[Newb alert]
i wish to start a server that will allow multipile connections at once at first i thout about forking but then i realized that it will consume alot of resorses.

so i started googling about threads and i thout that it is wiser to use threads for this condition .
as from example on socket for linux tutorial

Code:

---

while (1)
 {
  newsockfd = accept(sockfd,
              (struct sockaddr *) &cli_addr, &clilen);
  if (newsockfd < 0)
    error("ERROR on accept");
  pid = fork();
  if (pid < 0)
    error("ERROR on fork");
  if (pid === 0)
  {
    close(sockfd);
    dostuff(newsockfd);
    exit(0);
  }
  else
    close(newsockfd);
 } /* end of while */

---

what will be the apropreate code with treads ?


P.s.
my server will get a string from a uniqe client accses a database retrive a aporeate data from database
start sevral function on this data
and return an answer to the client

Page four of the following PDF has a short introduction on threading a server:
