  28  * Basic Networking Types
  29  *
  30  * This module is responsible for defining the following basic networking
  31  * types:
  32  *
  33  *              struct in_addr
  34  *              struct in6_addr
  35  *              struct sockaddr
  36  *              struct sockaddr_in
  37  *              struct sockaddr_in6
  38  *
  39  * It ensures that the AF_ and PF_ macros are defined.
  40  *
  41  * It declares ntoh[sl]() and hton[sl]().
  42  *
  43  * It declares lwres_net_aton(), lwres_net_ntop(), and lwres_net_pton().
  44  *
  45  * It ensures that INADDR_LOOPBACK, INADDR_ANY and IN6ADDR_ANY_INIT
  46  * are defined.
