Question

Socket has a constructor that takes a winsock SOCKET as parameter and stores it in a private variable:

Socket::Socket(SOCKET s) {     this->s = s; } 

I’m trying to make a class ‘GameSocket’ that will parse data from my Socket class:

class GameSocket : public Socket {  protected:      void ParseData(unsigned char* data, int size);  }; 

Next to these classes, I have a ‘Server’ class that creates new sockets when needed:

GameSocket* Server::Accept() {      SOCKET a = accept(s, 0, 0);     if(a==SOCKET_ERROR) {         return 0;     }     else {         return new GameSocket(a);     }  } 

However, this gives me an error on the last ‘else’:

error C2664: 'GameSocket::GameSocket' : cannot convert parameter 1 from 'SOCKET' to 'const GameSocket &' 

I must be missing something with constructors when dealing with derived classes…

Don’t go too hard on me, I’m relatively new to C++ and OOP

Add in a constructor for GameSocket

class GameSocket : public Socket {  public:      // you need to add     GameSocket(SOCKET s) : Socket(s) {}  protected:      void ParseData(unsigned char* data, int size);  };
