名称
unlock_mutexT_unlock_mutexUnlockMutexUnlockMutexunlock_mutex — Unlock a mutex synchronization object.
参数签名
描述
unlock_mutexunlock_mutexUnlockMutexUnlockMutexUnlockMutexunlock_mutex unlocks the mutex object given by MutexHandleMutexHandleMutexHandleMutexHandlemutexHandlemutex_handle.
The mutex is assumed to be locked and owned by the calling thread. Unlocking
a mutex that is already unlocked has no effect.
运行信息
- Multithreading type: independent (runs in parallel even with exclusive operators).
- 多线程作用域:全局(可以从任何线程调用)。
- 未经并行化处理。
