socket_bind6(3)       DragonFly Library Functions Manual       socket_bind6(3)

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);
