NAME
       socket_send6 - send a UDP datagram

SYNTAX
       #include <socket.h>

       ssize_t socket_send6(int s, const char* buf, size_t len,
                const char ip[16], uint16 port, uint32 scope_id);

DESCRIPTION
       socket_send6 sends len bytes starting at buf in a UDP datagram over the
       socket s to UDP port port on IP address ip.

       You can call socket_send6 without calling socket_bind6.  This has the
       effect as first calling socket_bind6 with IP address :: and port 0.

       The meaning of scope_id is dependent on the implementation and IPv6 IP.
       On link-local IPv6 addresses it specifies the outgoing interface index.
       The name (e.g. "eth0") for a given interface index can be queried with
       getifname.  scope_id should normally be set to 0.

RETURN VALUE
       socket_send6 returns 0 if the datagram was sent successfully.  If not,
       it returns -1 and sets errno appropriately.

EXAMPLE
         #include <socket.h>

         int s;
         char ip[16];
         uint16 p;
         uint32 scope_id;

         s = socket_tcp4();
         socket_bind6(s,ip,p);
         socket_send6(s,"hello, world",12,ip,p,scope_id);
