how to get sender address in select system call?

[vlrk]

Hello all,

previously i was using accept() API for my socket connections,As my requirement changed where i need to listien on multiple socket fds, i used select system call.



my accept code is like below

accept(sockfd,(struct sockaddr*)&their_addr,&sin_size)

Now my select call is like below.

select(serverSocket2 + 1, &fdset, NULL, NULL, NULL);

Now how can i get the sender address in this select call..?

Thanks all

Basically, a loop over all valid file descriptors

for ( i = 0 ; i <= serverSocket2 ; i++ ) {
  if ( FD_ISSET(i,&fdset) ) {
    // do something with fd i
  }
}

when the select call indicates the server socket is readable as Salem shows, that's when you do an 'accept' and get the client address. "In order to be notified of incoming connections on a socket, you can use select(2) or poll(2). A readable event will be delivered when a new connection is attempted and you may then call accept() to get a socket for that connection"
