What is the *proper* way to perform an change-working-directory from C?
Ditto a get-working-directory?

(That is "cd place" and "cd" from the CLI.)

As per Rob Peck's book, I did the following for the getcwd() --

	me = FindTask(0);
	success = Examine(me->pr_CurrentDir, &fib);
	printf("Current directory: %s\n", fib.fib_FileName);

However, this doesn't include the disk name.  Arg.

As for the chdir() --

	if (i created an earlier directory lock) UnLock(oldlock);
	myLock = Lock(dname, ACCESS_READ);
	dummyreturn = ChangeDir(myLock);

Rob's book indicates I shouldn't unlock any lock I didn't create.
But doesn't this leave a lock on the old directory sitting around?
Shouldn't I just do this:

	myLock = Lock(dname, ACCESS_READ);
	oldlock = ChangeDir(myLock);
	if (oldlock != NULL)
		UnLock(oldlock);

But Rob's book says this'll piss off DOS.

Am I going about all this the hard way?  I'm using Manx and couldn't find
equivalent routines in their library, but it *was* late and dark and....
