Suppose a program creates a socket and doesn't bind it to a local 
address.  When the program wants to connect the socket to a remote 
address (for TCP) or send a datagram to a remote address (for UDP or 
raw IP), the kernel automatically assigns a local address to it.

Questions:

	1. What algorithm does the kernel use to select the local 
	   address?

	2. Where is the source code for the selection?

	3. Is this information documented anywhere?

Thank you,

Alan Stern
