Hello all,

One quick question.  In the header of an IP datagram sent to a TCP/IP host
there are two fields: SOURCE ADDRESS and DESTINATION ADDRESS.  As far as
I have read, once the packet is sent, these two fields are never modified.

First, is this in fact true?
Second, what C system calls exist to access the information in these fields?

After a couple of days I have not been able to figure out how to retrieve
either the of the addresses from incoming datagrams.  Any help, or pointers
to the appropriate manpages would be greatly appreciated.
