XMPP（可扩展消息处理现场协议）的无界面插件库-XMPP (Extensible Messaging and Presence Protocol) library of non-interface plug-ins

此程序是一个直接序列扩频与跳频混合的扩频通信系统的仿真，扩频码用的是线性移位寄存器产生的m序列，跳频的跳点数为4。

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.

pl/sql的综合运用上例用到的oracle里关于游标的几个内置函数:％isopen,％notfound,％rowcount。 隐式游标更多用在for loop中，你不用再手工去open，fetch或是close游标，非常方便-pl/sql integrated the use of oracle used in Example cursor on several built-in functions: isopen, notfound, rowcount. Implicit cursor more used in for loop, you no longer have to manually open, fetch or close the cursor, a very convenient
