clear_mutexT_clear_mutexClearMutexClearMutexclear_mutex — Clear the mutex synchronization object.

Signature

clear_mutex( : : MutexHandle : )

Description

clear_mutexclear_mutexClearMutexClearMutexClearMutexclear_mutex destroys the mutex object given by MutexHandleMutexHandleMutexHandleMutexHandlemutexHandlemutex_handle. The mutex must be unlocked.

Multithreading type: independent (runs in parallel even with exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

This operator modifies the state of the following input parameter:

MutexHandleMutexHandleMutexHandleMutexHandlemutexHandlemutex_handle

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