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.
