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

结果

If the condition handle is valid, the operator signal_conditionsignal_conditionSignalConditionSignalConditionSignalConditionsignal_condition 返回 2 ( H_MSG_TRUE )。如有必要，则抛出异常。
