虽然Windows下可视化开发工具如VC、Delphi、C＋＋ Builder等都有专用的定时器控件Timer，而且使用很方便，可以实现一定的定时功能，但最小计时精度仅为55ms，且定时器消息在多任务操作系统中的优先级很低，不能得到及时响应，往往不能满足实时控制环境下的应用。不过Microsoft公司在Win32 API函数库中已经为用户提供了一组用于高精度计时的底层函数，如果用户使用得当，计时精度可到1ms。这个计时精度、对于一般的实时系统控制完全可以满足要求。现将由C＋＋ Builder 4.0提供的重新封装后的一组与时间相关的主要接口函数（函数名、参数、功能与Win32 API基本相同）说明如下：
-visual development tools such as Visual C++, Delphi, C++ Builder and others all have dedicated Timer timer control, but it is convenient. can achieve a timing function, but only the minimum time of 55 ms accuracy. Timer news and multi-task operating system in the low priority that is not to respond in a timely manner, often fail to meet the real-time control environment applications. However, Microsoft Corporation in the Win32 API function has been to provide the user with a group for high-precision the bottom was a time function, if the user is properly utilized, time accuracy can be a ms. Accuracy this time, and for most of the real-time control system can meet the requirements.

操作系统有所耳闻，它是微软已推出的三种操作系统内核之一，是一种实时操作系统。虽然它是一种实时操作系统，但是从96年发布v1.0到现在，它的主要用途都在民用领域，比如Pocket
PC、SmartPhone、Automation。不像VxWorks，应用于航空航天、军事等领域。现在linux、VxWorks厂商也都看好嵌入式民用市场，激烈竞争在所难免。我看好Windows
CE，因为微软在PC领域实在太强，用户也早已熟悉了微软的产品，把PC下的技术移植到嵌入式领域，首先在操作界面方面就占了上风。
-operating systems have heard, it is Microsoft has launched three of the operating system kernel, is a real-time operating system. Although it is a real-time operating system, but from the 96 released v1.0 now, which are mainly used in civilian areas, such as Pocket PC, SmartPhone, Automation. Like VxWorks, used in aerospace, military and other fields. Now Linux, VxWorks manufacturers are optimistic about embedded civilian market, fierce competition is inevitable. I like Windows CE, Microsoft in the PC field is too strong, users are already familiar with Microsoft products, the PC technology into the embedded field in the first operation on the interface prevailed.
