Hmmm... chdir(2) would not change the parent process' (the shell's
process) current working directory, only the current working directory
of the process running the C program.

Perhaps connecting to the shell via a pty, and then sending it a 'cd'
command could work? Of look at how expect(1) (/usr/ports/lang/expect)
implements this kind of stuff...
