For a client (that is, when you call connect), the kernel chooses the 
source IP address once the socket is connected.

Of course, for a server this is not feasible, since the address *must* 
be know to external programs, if they want to connect to the server.


For more details, I really suggest to read a good book like
"UNIX Network Programming", by W. Richard Stevens.
