Yes, the documentation does indicate this method of indicating end of 
file, or the closing of the connection by the other end.

"- void tcp_recv(struct tcp_pcb *pcb,
                err_t (* recv)(void *arg, struct tcp_pcb *tpcb,
                               struct pbuf *p, err_t err))

  Sets the callback function that will be called when new data
  arrives. The callback function will be passed a NULL pbuf to
  indicate that the remote host has closed the connection."
