 SUSv3 says for sendto():
 
   [EISCONN] A destination address was specified and the socket is already
   connected. This error may or may not be returned for connection mode
   sockets.
 
 FreeBSD does it in the first way (whereas Linux in the second) and the
 error in case of non-NULL destination address is reported. However, the
 manual page is quiet about it:
