This should do it.  Randell will pipe in if I got it wrong...   ;-)

/* get a lock on the desired directory. */
if (0 != (lock = Lock(name,accessMode)))
    oldLock = CurrentDir(lock);     /* change current dir */

/* run program given new current dir.
** the program will run here if it cannot get the lock,

*/
runProgram();

if (0 != lock) /* only change back and unlock if we got it. */
    {
    CurrentDir(oldLock);   /* change back to original dir */
    UnLock(lock);
    }
