Is there a simple, portable way to discover the outgoing IP address of a datagram socket on a multi-homed host?
...that is... I want to send a browser message. I know the destination address (a host address or the local broadcast address). Once I open the socket I can use getsockname(2) to discover the outgoing port number (that is, the source port). The problem is that getsockname(2) returns INADDR_ANY (0.0.0.0), which is reasonable since the system doesn't know the outbound interface address until the message gets routed. So, is there any portable way to ask the system which IP address (which interface, I suppose) will be used as the source address before sending the datagram?
