名称
timed_wait_conditionT_timed_wait_conditionTimedWaitConditionTimedWaitConditiontimed_wait_condition — Bounded wait on the signal of a condition synchronization object.
参数签名
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.
运行信息
- Multithreading type: independent (runs in parallel even with exclusive operators).
- 多线程作用域:全局(可以从任何线程调用)。
- 未经并行化处理。
参数表
ConditionHandleConditionHandleConditionHandleConditionHandleconditionHandlecondition_handle (input_control) condition → HCondition, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Condition synchronization object.
MutexHandleMutexHandleMutexHandleMutexHandlemutexHandlemutex_handle (input_control) mutex → HMutex, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Mutex synchronization object.
TimeoutTimeoutTimeoutTimeouttimeouttimeout (input_control) number → HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)
Timeout in micro seconds.
结果
timed_wait_conditiontimed_wait_conditionTimedWaitConditionTimedWaitConditionTimedWaitConditiontimed_wait_condition returns 2 (
H_MSG_TRUE)
if all parameters are correct.
如有必要，将引发异常。 If a timeout occurs, the error
H_ERR_TIMEOUT is raised.
