[in, optional] TimerQueue 计时器队列的句柄。 此句柄由CreateTimerQueue函数返回。 如果此参数为NULL,则计时器与默认计时器队列相关联。 [in] Callback 指向在计时器过期时要执行的WAITORTIMERCALLBACK类型的应用程序定义函数的指针。 有关详细信息,请参阅WaitOrTimerCallback。
for(vari = 1; i <= 5; i++) { setTimeout(functiontimer() { console.log(i) }, i * 1000) } 输出结果大家都只是会是5个6,由于JavaScript是单线程的,按顺序执行,setTimeout是异步函数,它会将timer函数放到任务队列中,而此时会先将循环执行完毕再执行timer函数,因此当执行timer函数时i已经等于6了,...

* These timers are currently used for: * - itimers * - POSIX timers * - nanosleep * - precise in-kernel timing * 2. 用户层定时器API接口 上面介绍完linux内核定时器的实现后,下面简单说一下,基于内核定时器实现的,对用户层开放的定时器API:间隔定时器itimer和POSIX定时器。
