我无法在 Windows（C 语言）上使用绑定方法。出色地。我的代码应该做以下事情：
- 从用户那里获取 2 个地址：一个必须是本地计算机的 IP 地址，另一个必须是远程地址（例如 google 地址）。
- 我正在编写的应用程序将绑定到本地地址
- 应用程序将连接到第二个地址。
我从网上得到了一些代码。您可以查看我在评论中咨询过的所有来源。
This application will only accepts a string from the client (which specifies the local
address which the application will bind), then, the app will connect to a remote service
google, youtube or whatever. The main purpose that this app serves is to know if, when
binded to a local address, the operative system (in this case Windows Based system) gives priority to:
- SA/DA rule
- Forwarding table

问题是绑定返回-1。我已经测试过了。
谁可以帮我这个事？
