描述

timed_wait_conditiontimed_wait_conditionTimedWaitConditionTimedWaitConditionTimedWaitConditiontimed_wait_condition atomically unlocks MutexHandleMutexHandleMutexHandleMutexHandlemutexHandlemutex_handle and waits on ConditionHandleConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle, as wait_conditionwait_conditionWaitConditionWaitConditionWaitConditionwait_condition does, but it also bounds the duration of the wait. If ConditionHandleConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle has not been signaled within the amount of time specified by TimeoutTimeoutTimeoutTimeouttimeouttimeout in micro seconds, the mutex MutexHandleMutexHandleMutexHandleMutexHandlemutexHandlemutex_handle is re-acquired and timed_wait_conditiontimed_wait_conditionTimedWaitConditionTimedWaitConditionTimedWaitConditiontimed_wait_condition returns the error H_ERR_TIMEOUT.

Using negative values for TimeoutTimeoutTimeoutTimeouttimeouttimeout means an infinite waiting time.

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

timed_wait_conditiontimed_wait_conditionTimedWaitConditionTimedWaitConditionTimedWaitConditiontimed_wait_condition 在所有参数正确时返回 2 ( H_MSG_TRUE )。如有必要，则抛出异常。如果发生超时，将抛出错误 H_ERR_TIMEOUT。
