NAME
       socket_recv6 - receive a UDP datagram

SYNTAX
       #include <socket.h>

       ssize_t socket_recv6(int s, char* buf, size_t len,
	       char ip[16], uint16* port, uint32* scope_id);

DESCRIPTION
       socket_recv6  receives  up  to len bytes starting at buf from a UDP datagram coming in on the socket s.	It writes the UDP port to port and
       the IP address to ip, and returns the number of bytes actually received (or -1 if anything went wrong).

       For link-local addresses, scope_id will become the network interface number, which can  be  translated  into  the  name	of  the  interface
       ("eth0") with socket_getifname.

RETURN VALUE
       socket_recv6 returns the number of bytes in the datagram if one was received.  If not, it returns -1 and sets errno appropriately.

EXAMPLE
	 #include <socket.h>

	 int s;
	 char ip[16];
	 uint16 p;
	 char buf[1000];
	 int len;
	 uint32 scope_id;

	 s = socket_tcp4();
	 socket_bind6(s,ip,p);
	 len = socket_recv6(s,buf,sizeof(buf),ip,&p,&scope_id);
