名称

unlock_mutexT_unlock_mutexUnlockMutexUnlockMutexunlock_mutex — Unlock a mutex synchronization object.

签名

unlock_mutex( : : MutexHandle : )

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.

执行信息

多线程类型：独立（即使使用独占算子也能并行运行）。
多线程作用域：全局（可从任何线程调用）。
未采用并行化处理。

参数

MutexHandleMutexHandleMutexHandleMutexHandlemutexHandlemutex_handle (输入控制) mutex → (handle)

Mutex synchronization object.

结果

If the mutex handle is valid, the operator unlock_mutexunlock_mutexUnlockMutexUnlockMutexUnlockMutexunlock_mutex 返回 2 ( H_MSG_TRUE )。如有必要，则抛出异常。
