socket_bind6 - set the local IP address and port of a socket
#include <socket.h>
int socket_bind6(int s, char ip[16], uint16
port,
uint32 scope_id);
socket_bind6 sets the local IP address and TCP/UDP port of a TCP/UDP socket s to ip and port respectively.
If the IP address is ::, the operating system chooses a local IP address. If port is 0, the operating system chooses a port.
Normally socket_bind6 returns 0. If anything goes wrong, socket_bind6 returns -1, setting errno appropriately.
The scope_id should normally be zero, but for link-local addresses it specifies the interface number on which to bind. The interface number for a given network interface name can be found with socket_getifidx.
#include <socket.h>

char ip[16];
uint16 p;

s = socket_tcp6();
socket_bind6(s,ip,p,scope_id);
socket_connect6(s,ip,p);
