NAME
socket_local6 - get local IP address of socket
SYNTAX
#include <socket.h>
int socket_local6(int s,char ip[16],uint16 *port,uint32 *scope_id);
DESCRIPTION
socket_local6 returns the local IPv6 address, port and scope ID for the UDP or TCP socket s and writes the IPv6 address to ip, the port to port and the scope ID to scope_id.
If scope_id is the null pointer, socket_local6 will discard the scope ID.
