select server send buf pointer mistake

[wangdingqiao]

in function on_peer_ready_send from file : select-server.c

fd_status_t on_peer_ready_send(int sockfd) {
  assert(sockfd < MAXFDs);
  peer_state_t* peerstate = &global_state[sockfd];

  if (peerstate->sendptr >= peerstate->sendbuf_end) {
    // Nothing to send.
    return fd_status_RW;
  }
  int sendlen = peerstate->sendbuf_end - peerstate->sendptr;
  int nsent = send(sockfd, peerstate->sendbuf, sendlen, 0);
  // ...
  if (nsent < sendlen) {
    peerstate->sendptr += nsent;
    return fd_status_W;
  } else {
    // Everything was sent successfully; reset the send queue.
    peerstate->sendptr = 0;
    peerstate->sendbuf_end = 0;
   // ...
  }
}

I think this line:

int nsent = send(sockfd, peerstate->sendbuf, sendlen, 0);

shoule be:

int nsent = send(sockfd, peerstate->sendbuf+peerstate->sendptr, sendlen, 0);

Thank you! Fixed it in the code and will fix in the blog post too
