我是Modelica的新手，我正尝试将我的模型链接到外部socketdll，但我不知道是什么原因导致了错误。函数中指示的文件路径是否错误？谢谢
function constructor
input String ip = "127.0.0.1";
output MySocket SocketClient;
external "C" SocketClient = SocketInitConnect(ip)annotation (Include = "#include \"SocketDll.h\"",
IncludeDirectory = "modelica://exfuncExample/Resources/include",
Library = "SocketDll",
LibraryDirectory = "modelica://exfuncExample/Resources/libs");
end constructor;
