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