In the include files supplied by Manx, functions such as Lock, DupLock,
CurrentDir are declared as returning pointers to struct Lock.  However,
there is no struct Lock defined in the include files.  Instead, most of
the documentation (ALL of the documentation) casts the result of these
functions to struct FileLock.  Furthermore, when I try to look at the
field fd_Task of a lock, my system crashes.  Can anyone explain this to
me?

P.S.  By look at, I mean that if I execute the statement
task = lock->fl_Task, my system crashes.
