1.线程池管理器（ThreadPoolManager）:用于创建并管理线程池
2.工作线程（WorkThread）: 线程池中线程
3.任务接口（Task）:每个任务必须实现的接口，以供工作线程调度任务的执行。
4.任务队列:用于存放没有处理的任务。提供一种缓冲机制。
网上的c/c++线程池多是linux下的，这个是VC6.0的线程池。其涉及的主要文件有：ThreadPoolManage、IThreadExcute、TemporarilyThread、ThreadManage、RegKeyIni。(1. thread pool manager (ThreadPoolManager): for creating and managing the thread pool　　　　　　2. working thread (WorkThread): thread in the thread pool　　　　　　3. task interface (Task): the interface that each task must be implemented for the working thread to schedule the task execution.　　　　　　4. task queue: it is used to store unprocessed tasks. Provide a buffer mechanism.　　　　　　The c/c++ thread pool on the Internet is mostly under Linux, and this is the thread pool of VC6.0. The main documents involved are: ThreadPoolManage, IThreadExcute, TemporarilyThread, ThreadManage, RegKeyIni.)
