/* Convenient macro for testing for deadlock, as well as for detecting
 * when mutexes fail.
 *
 * The parameters to the ACE_GUARD_XXX macros are used as follows:
 *
 * MUTEX - This is the type used as the template parameter for ACE_Guard
 *
 * OBJ - Name for the guard object. This name should not be declared
 *       outside the macro.
 *
 * LOCK - The actual lock (mutex) variable. This should be a variable
 *        of type MUTEX, see above.
 *
 * ACTION - Code segment to be run, if and only if the lock is
 *          acquired.
 *
 * REACTION - Code segment to be run, if and only if the lock is not
 *            acquired.
 *
 * RETURN - A value to be returned from the calling function, if and
 *          only if the lock is not acquired.
 *
 * @warning
 *   Use of ACE_GUARD() is rarely correct.  ACE_GUARD() causes the
 *   current function to return if the lock is not acquired.  Since
 *   merely returning (no value) almost certainly fails to handle the
 *   acquisition failure and almost certainly fails to communicate the
 *   failure to the caller for the caller to handle, ACE_GUARD() is
 *   almost always the wrong thing to do.  The same goes for
 *   ACE_WRITE_GUARD() and ACE_READ_GUARD() .  ACE_GUARD_REACTION() is
 *   better because it lets you specify error handling code.
