windows定时器编程 Sleep和 SleepEx函数

一个windows编程示例：

#include <iostream>
#include <windows.h> 
#include <stdio.h>

using namespace std;

static  int COUNT = 0;

VOID CALLBACK TimerRoutine(PVOID lpParameter, BOOLEAN TimerOrWaitFired)
{
    if (NULL == lpParameter)
    {
        cout << "TimerRoutine parameter is NULL!" << endl;
        return;
    }

    printf("the values of param is :%d\n", *(int*)lpParameter);
}

int main(int argc, TCHAR *argv[])
{
    HANDLE m_hTimerQueueTimer = NULL;
    HANDLE m_hTimerQueue = NULL;

    while (NULL == (m_hTimerQueue = CreateTimerQueue())) {
        cout << "Create timer queue failed!" << endl;
        Sleep(10);
    }

    while (!CreateTimerQueueTimer(&m_hTimerQueueTimer, m_hTimerQueue, WAITORTIMERCALLBACK(TimerRoutine), &COUNT, 1000, 1000, NULL))
    {
        cout << "Create timer failed!" << endl;
        Sleep(10);
    }

    while (1) {
        Sleep(1000);
        COUNT++;
    }

    if (m_hTimerQueueTimer != NULL)
        DeleteTimerQueueTimer(m_hTimerQueue, m_hTimerQueueTimer, INVALID_HANDLE_VALUE);
    if (m_hTimerQueue != NULL)
        DeleteTimerQueueEx(m_hTimerQueue, INVALID_HANDLE_VALUE);

    m_hTimerQueueTimer = NULL;
    m_hTimerQueue = NULL;


    return 0;
}
