socket_bind6 - set the local IP address and port of a socket
Contents
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 <libowfat/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);
