如何定期唤醒C++ 11线程？

#include <iostream>
#include <thread>
#include <chrono>
#include <mutex>
#include <condition_variable>

std::mutex mtx;
std::condition_variable cv;
bool isReady = false;

void workerThread()
{
    while (true)
    {
        std::unique_lock<std::mutex> lock(mtx);
        // 等待条件满足
        cv.wait(lock, []{ return isReady; });

        // 执行需要定期执行的任务
        std::cout << "Worker thread is executing..." << std::endl;

        // 任务完成后重置条件
        isReady = false;
        lock.unlock();
    }
}

int main()
{
    // 创建工作线程
    std::thread worker(workerThread);

    // 定期唤醒工作线程
    while (true)
    {
        std::this_thread::sleep_for(std::chrono::seconds(5));

        std::lock_guard<std::mutex> lock(mtx);
        isReady = true;
        cv.notify_one();
    }

    // 等待工作线程结束
    worker.join();

    return 0;
}
