Thread: Function in a Server program

Hi to All,

I have written a little server that work fine.
Now I need to add a function in the main that process a phrase, passed from a client as telnet. The last part of main is:

Code:

listen(sock, 1);
/* connection client */
while (1) {
  client_len = sizeof(client);
  if ((fd = accept(sock, (struct sockaddr *)&client, &client_len)) < 0) {
     perror("accepting connection");
     exit(3);
  }
  fprintf(stderr, "The connection is Open.\n");
  send(fd, "Wellcome in my Server !\n\n", 38, 0);
  send(fd, "Please send Your Phrase, terminated by ..)!\n\n", 44, 0);
  process_phase(fd,fd);
  close(fd);
  fprintf(stderr, "The Connection is Closed.\n");
  }

fd is the socket descriptor and the function is like:
void process_phrase(int in, int out);

How must write the code that read the phrase until the client send the terminator signal ".."

I hope in Your help. I am a newbie in C programming.

Thank You and Best Regards.
