28 ** PARSEADDR -- Parse an address
30 ** Parses an address and breaks it up into three parts: a
31 ** net to transmit the message on, the host to transmit it
32 ** to, and a user on that host. These are loaded into an
33 ** ADDRESS header with the values squirreled away if necessary.
34 ** The "user" part may not be a real user; the process may
35 ** just reoccur on that machine. For example, on a machine
36 ** with an arpanet connection, the address
37 ** csvax.bill@berkeley
38 ** will break up to a "user" of 'csvax.bill' and a host
39 ** of 'berkeley' -- to be transmitted over the arpanet.
42 ** addr -- the address to parse.
43 ** a -- a pointer to the address descriptor buffer.
