NAME¶
socket_bind6 - set the local IP address and port of a socket
SYNTAX¶
#include <socket.h>
int
socket_bind6(int
s, char
ip[16], uint16
port,
uint32
scope_id);
DESCRIPTION¶
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.
EXAMPLE¶
#include <socket.h>
int
s;
char
ip[16];
uint16
p;
uint32
scope_id;
s = socket_tcp6();
socket_bind6(s,ip,p,scope_id);
socket_connect6(s,ip,p);
