28 * This module is responsible for defining the following basic networking
34 *\li struct sockaddr_in
35 *\li struct sockaddr_in6
37 * It ensures that the AF_ and PF_ macros are defined.
39 * It declares ntoh[sl]() and hton[sl]().
41 * It declares lwres_net_aton(), lwres_net_ntop(), and lwres_net_pton().
43 * It ensures that #INADDR_LOOPBACK, #INADDR_ANY and #IN6ADDR_ANY_INIT
