clear_mutexT_clear_mutexClearMutexClearMutexclear_mutex — Clear the mutex synchronization object.

clear_mutex( : : MutexHandle : )

clear_mutexclear_mutexClearMutexClearMutexClearMutexclear_mutex destroys the mutex object given by MutexHandleMutexHandleMutexHandleMutexHandlemutexHandlemutex_handle. The mutex must be unlocked. After calling clear_mutexclear_mutexClearMutexClearMutexClearMutexclear_mutex, the mutex can no longer be used. The handle MutexHandleMutexHandleMutexHandleMutexHandlemutexHandlemutex_handle becomes invalid.

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。

This operator modifies the state of the following input parameter:

During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.

Mutex synchronization object.

If the mutex handle is valid, 该算子 clear_mutexclear_mutexClearMutexClearMutexClearMutexclear_mutex returns 2 ( H_MSG_TRUE) . 如有必要，将引发异常。
