本文详细介绍了在Windows系统中使用C++实现线程池的各个关键类，包括CThread（线程基类）、CWorkerThread（工作线程）、CThreadPool（线程池管理）、CJob（任务类）、CThreadCondition（线程同步）和CThreadMutex（线程互斥）。这些类分别负责线程的创建与销毁、任务的管理和执行、线程的调度与管理、任务执行逻辑、线程间的同步以及互斥锁的实现。此外，还提到了CThreadManage类作为上层接口，用于操作线程池的启动和销毁。

工作当中频繁使用到多线程，网上参考了一份代码，并根据自己需要改进了一下，贴出来做个记录，以后如果有产生问题还会继续改进。
大致介绍下每个类的作用：
1. CThread 线程基类，线程创建及销毁
2. CWorkerThread 工作线程，任务设置获取，池对象设置获取，线程运行及终止
3. CThreadPool 任务运行，空闲线程/忙碌线程管理，销毁线程池
4. CJob 需要执行的任务类，业务逻辑可继承此类
5. CThreadCondition 线程同步，条件变量类，由event触发等待实现
6. CThreadMutex 线程互斥，由临界区实现
7. CThreadManage 暴露给上层的类，主要集中线程池的运行与销毁
以下是各个文件的实现代码，记录一下：
