==================================================================

10035
1、对已使用非阻塞的套接字，又进行阻塞方式的接收式出现此错误

10038
1、对无效的套接(invalid_socket)字进行读取出报此错误

10048
1、端口、IP地址已被占用时报此错误

10014
1、Server端TCP，使用WSAAsyncSelect来接收FD_ACCEPT等消息，当窗口为最小化或者不是活动窗口里，处理FD_ACCEPT消息时，使用如下代码：accept(FSrvSock, @cAddrIn, @addrLen); addrLen未初始化，导致返回该错误代码，添加 addrLen := SizeOf(cAddrIn);初始化后问题解决。

10040
1、接收时接收的buffer为integer，发送端发送的为两个Integer，所以接收时出现此错误。
