signal_conditionT_signal_conditionSignalConditionSignalConditionsignal_condition（算子）
名称
signal_conditionT_signal_conditionSignalConditionSignalConditionsignal_condition — Signal a condition synchronization object.
签名
描述
signal_conditionsignal_conditionSignalConditionSignalConditionSignalConditionsignal_condition restarts one of the threads that are waiting on the
condition variable ConditionHandleConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle. If no threads are waiting on
ConditionHandleConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle, nothing happens. If several threads are waiting on
ConditionHandleConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle, exactly one is restarted, but it is not specified
which one.
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
ConditionHandleConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle (输入控制) condition → HCondition, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
条件同步对象。
结果
如果条件句柄有效，则算子 signal_conditionsignal_conditionSignalConditionSignalConditionSignalConditionsignal_condition 返回 2 (H_MSG_TRUE)。如有必要，则抛出异常。
