socket_bind6(3) Library Functions Manual socket_bind6(3)


socket_bind6 - set the local IP address and port of a socket


#include <socket.h>

int socket_bind6(int s, char ip[16], uint16 port, uint32 scope_id);


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.


#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);
