Signature

clear_condition( : : ConditionHandle : )

Herror T_clear_condition(const Htuple ConditionHandle)

void ClearCondition(const HTuple& ConditionHandle)

void HCondition::ClearCondition() const

static void HOperatorSet.ClearCondition(HTuple conditionHandle)

void HCondition.ClearCondition()

def clear_condition(condition_handle: HHandle) -> None

Description

clear_conditionclear_conditionClearConditionClearConditionclear_condition destroys the condition object given in ConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle. No threads should be waiting on the condition at the time clear_conditionclear_conditionClearConditionClearConditionclear_condition is called. After calling clear_conditionclear_conditionClearConditionClearConditionclear_condition, the condition can no longer be used. The handle ConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle becomes invalid.

• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

This operator modifies the state of the following input parameter:

• ConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle

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

Parameters

ConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle (input_control, state is modified)  condition → HCondition, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Condition synchronization object.
