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.

摘要 TCP 软件一般位于操作系统的核心，这种情况给TCP 的研究和调试带来了很大的困难。 在Sun Solaris 平台上，我们使用系统提供的DLPI 接口和有关多线程的系统调用，构建了一 个TCP 调试系统，简化了调试过程。 关键字 TCP，调试系统，DLPI，多线程-Abstract TCP software at the core of the operating system. This situation TCP research and testing has led to great difficulties. Sun Solaris platform, We use the system to provide the interface and the TCP multithreaded system calls, built a TCP debugging system, simplifies the debugging process. Keywords TCP, debugging system, Solaris, multithreading

应用背景 通过MFC6.0生成一个单文档程序，然后新建一个对话框并生成一个新类；在对话框中添加两个组合框控件。在生成的新类上右击增加windows消息WM_INITDIALOG生成处理函数，函数内容见“关键技术描述”。函数体中的index和baud均为int型，可设为全局变量。 关键技术BOOL CComDlg::OnInitDialog()  { CDialog::OnInitDialog(); ((CComboBox *)GetDlgItem(IDC_COMBO2))->AddString("4800"); ((CComboBox *)GetDlgItem(IDC_COMBO2))->AddString("9600"); ((CComboBox *)GetDlgItem(IDC_COMBO2))->AddString("38400"); ((CComboBox *)GetDlgItem(IDC_COMBO2))->AddString("115200"); ((CComboBox *)GetDlgItem(IDC_COMBO2))->SetCurSel(0+baud); long lReg;   HKEY hKey;   DWORD MaxValueLength;
