在我的代码中出现这个"10038 wsa socket"错误

我当前正在尝试实现一个类来创建和使用TCP连接。

（我在C 中很新，所以即使我一直在认真检查我的代码，我也可能忘记了一些明显的东西）

请注意，稍后我将实施第二类来处理新的连接，因此代码的某些部分不完整/安排，我希望这不会在尝试理解它时不会打扰您。

这是我的问题：

服务器和客户端似乎都可以正常工作（我一直在检查我的收听，绑定，连接函数：无错误），显然我可以与客户端发送数据，但是当我尝试阅读它时从服务器中，我获得WSA错误10038（这意味着我正在无效套接字上执行RECV（））。我已经看了几天了，似乎找不到我的错误。除了代码中的测试外，我还使用了" NetStat -An -P TCP"。要检查连接的状态并且一切看起来都很好，但是服务器只是无法接收数据。

nb：我正在使用Visual Studio 6（是的，它旧了，但这是强制性的...）和Winsock，而不是Winsock2。

如果我忘记了一些东西，我想尽可能完整，但并非不可能忘记任何东西。

这是我的源代码，我试图将其切成必需品，但恐怕错误可能在任何地方：
