* Basic Networking Types
|
|
*
|
|
* This module is responsible for defining the following basic networking
|
|
* types:
|
|
*
|
|
* struct in_addr
|
|
* struct in6_addr
|
|
* struct sockaddr
|
|
* struct sockaddr_in
|
|
* struct sockaddr_in6
|
|
*
|
|
* It ensures that the AF_ and PF_ macros are defined.
|
|
*
|
|
* It declares ntoh[sl]() and hton[sl]().
|
|
*
|
|
* It declares lwres_net_aton(), lwres_net_ntop(), and lwres_net_pton().
|
|
*
|
|
* It ensures that INADDR_LOOPBACK, INADDR_ANY and IN6ADDR_ANY_INIT
|
|
* are defined.
