NAME

6       socket_recv6 - receive a UDP datagram
7

SYNTAX

9       #include <socket.h>
10
11       ssize_t socket_recv6(int s, char* buf, size_t len,
12               char ip[16], uint16* port, uint32* scope_id);
13

DESCRIPTION

15       socket_recv6  receives up to len bytes starting at buf from a UDP data‐
16       gram coming in on the socket s.  It writes the UDP port to port and the
17       IP address to ip, and returns the number of bytes actually received (or
18       -1 if anything went wrong).
19
20       For link-local addresses, scope_id will become  the  network  interface
21       number, which can be translated into the name of the interface ("eth0")
22       with socket_getifname.
23

RETURN VALUE

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

EXAMPLE

29         #include <socket.h>
30
31         int s;
32         char ip[16];
33         uint16 p;
34         char buf[1000];
35         int len;
36         uint32 scope_id;
37
38         s = socket_tcp4();
39         socket_bind6(s,ip,p);
40         len = socket_recv6(s,buf,sizeof(buf),ip,&p,&scope_id);
