/*
** A locking mechanism, built on the existing PRLock definition,
** is provided that will permit applications to define a Lock
** Hierarchy (or Lock Ordering) schema. An application designed
** using the Ordered Lock functions will terminate with a
** diagnostic message when a lock inversion condition is
** detected.
**
** The lock ordering detection is compile-time enabled only. In
** optimized builds of NSPR, the Ordered Lock functions map
** directly to PRLock functions, providing no lock order
** detection.
**
** The Ordered Lock Facility is compiled in when DEBUG is defined at
** compile-time. Ordered Lock can be forced on in optimized builds by
** defining FORCE_NSPR_ORDERED_LOCK at compile-time. Both the
** application using Ordered Lock and NSPR must be compiled with the
** facility enabled to achieve the desired results.
**
** Application designers should use the macro interfaces to the Ordered
** Lock facility to ensure that it is compiled out in optimized builds.
**
** Application designers are responsible for defining their own
** lock hierarchy.
**
** Ordered Lock is thread-safe and SMP safe.
