socket_send6(3) 					     Library Functions Manual						   socket_send6(3)

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);
