How about marking the sockets non-blocking and using select() or poll() (or eventports)?

Thanks ARun,Rick

Can I do some think like this
While(true)
{
sd = accept (listen_sd, (struct sockaddr*) &sa_cli,(int *) &client_len);
//trying to create threads
if(sd)
{
pthread_create(&ThreadA,pthread_attr_default,connection,&sd);
}

In broad handwaving terms, yes, but frankly, a thread per connection is overkill. It may be easier to code, but in terms of efficiency, I'm hardpressed to see where non-blocking I/O and select/poll wouldn't win-out. The only case would be if there was something one had to do per-connection that couldn't be done non-blocking.
