这是osip官方网站下载，osip2的源代码。非常有帮助的…

此程序为外部升级程序(需要主程序的调用),具体代码这里就不罗列了,还是自己看源代码吧.此程序主要的思路是通过读取服务器文件获得升级版本及升级地址,有新版本则下载 如果想做成内部升级程序(在主程序内部自动检测及自动升级),只需要在主程序启动时相关的代码即可,大家不仿试试,主要的思路与这个是差不多的,不同之处是怎么处理主程序的自动关闭与启动问题.-This program is an external upgrade (requires the main program call), the specific code is not listed here, or to look up the source code for it. The main idea of this procedure is obtained by reading the file server upgrade and update address, a new version If you want to get inside is to download the upgrade process (in the main program within the auto-detection and auto-upgrade), just start in the main program code can be related, we do not try to imitate, the main idea and this is about the same, different The Department is how to deal with the main program automatically shut down and startup problems.

在 Wi n d o w s套接字应用程序中对 I / O（输入／输出）操作进行管理。Wi n s o c k分别提供了“套接字模式”和“套接字 I / O模型” ，可对一个套接字上的 I / O行为加以控制。其中，套接字模式用于决定在随一个套接字调用时，那些 Wi n s o c k函数的行为。而另一方面，套接字模型描述了一个应用程序如何对套接字上进行的 I / O进行管理及处理。-Wi ndows socket at the application of I/O (input/output) operations management. Provide the Wi nsock " socket model" and the " socket I/O model" may be a socket on the I/O to control behavior. Among them, the model used to determine the socket with a socket call in, those acts of the Wi nsock function. On the other hand, describes the socket model how an application on the socket I/O for the management and treatment.
