broadcast_conditionT_broadcast_conditionBroadcastConditionBroadcastConditionbroadcast_condition广播条件（算子）

名称

broadcast_conditionT_broadcast_conditionBroadcastConditionBroadcastConditionbroadcast_condition — 向条件同步对象发送信号。

签名

broadcast_condition( : : ConditionHandle : )

描述

broadcast_conditionbroadcast_conditionBroadcastConditionBroadcastConditionBroadcastConditionbroadcast_condition 重新启动所有在条件变量 ConditionHandleConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle 上等待的线程。如果没有线程在 ConditionHandleConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle 上等待，则不会发生任何操作。

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 → (handle)

条件同步对象。

结果

如果条件句柄有效，则算子 broadcast_conditionbroadcast_conditionBroadcastConditionBroadcastConditionBroadcastConditionbroadcast_condition 返回 2 ( H_MSG_TRUE )。如有必要，则抛出异常。
