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.
