You can look up the home directory by doing a getpwuid(uid) call which
is in the C library.  Look at the getpwent man page for the structure of
the returned value.  The home directory is a field in the returned
structure.

Also if you run the program out of cron, the current working directory
of the program is the home directory of the user.
