These routines should ** return true if the mutex in their argument is held or not held, ** respectively, by the current thread. The implementation is ** not required to provided working implementations of these ** routines as their intended use is within assert() statements ** only. If the implementation does not provide working ** versions of these routines, it must at least provide stubs ** that always return true. |
