WebIf the owner of a mutex dies, the mutex can become inconsistent. pthread_mutex_consistent_np makes the mutex object, mutex, consistent after the death of its owner. Call pthread_mutex_lock () to acquire the inconstent mutex. The EOWNWERDEAD return value indicates an inconsistent mutex. WebIf mutex is a robust mutex and the owning thread terminated while holding the mutex lock, a call to pthread_mutex_lock () may return the error value [EOWNERDEAD] even if the process in which the owning thread resides has not terminated. In these cases, the mutex is locked by the thread but the state it protects is marked as inconsistent.
