c - Issue if polled on listening socket instead of binding fd -


in tcp server/client, polling on binding fd (fd received during socket connection , binded ip). wondering impact if polling on listening socket (socket fd received during accept call)? polling on listening socket can anyway have issue related close_wait state socket issue? sample code below:-

struct pollfd pfd;  pfd.fd = sockfd; /*listening socket fd got during accept call*/ pfd.events = pollin;  ret = poll(&pfd, 1, 60000);  if (ret == 0 || errno == eintr) {      *err = socket_err_read_timeout;     *size = 0;      return socket_failure;  }else if (ret < 0) {      close(sockfd);     return socket_failure; }  ret = recv(sockfd, content, *size , 0);  if (ret == -1) {      close(sockfd);     *size = 0;     return socket_failure;  } else if (ret == 0) {     close(sockfd);     *size = 0;     return socket_failure; }  *size = ret;  return socket_success;
