ctypes.ArgumentError when calling DLL functions with Python

Question

I\'m using ctypes to call functions in a DLL file according to a description file that describe the DLL functions\' parameters and returns. Here is one function in this DLL

Answer 1

I think the problem is in your C++ interface. I think if you change it to Function：BOOL InitNetwork(char * LocalIP,char * ServerIP,int LocalDeviceID);

your first call (without the keywords) should work but I think you might need to remove the quotes around the last argument (it is an int after all).
