I’m trying to get the hostname of the computer running my plugin with gethostname(char * name, int namelen) from winsock.h. I execute it in code like so:

#include "Player.h"
#include "winsock.h"
   
  Player::Player(_bstr_t connectionString)
  {
        _connectionString = connectionString;
   
        ::CoInitialize(NULL);
   
        _connectionPtr.CreateInstance(__uuidof(ADODB::Connection));
        
        if(_connectionPtr)
        {
              _connectionPtr->Open(_connectionString, "", "", 0);
        }
   
        GetServerSettings(GetHostname());
  }
   
  char* Player::GetHostname()
  {
        char* name = "";
        int nameLen = 50;
        ::gethostname(name, nameLen);
   
        return name;
  }
   
  void Player::GetServerSettings(char * hostname)
  {
        ADODB::_RecordsetPtr recordsetPtr = Provider::GetServerSettings(_connectionPtr, hostname);
   
        if(recordsetPtr && !recordsetPtr->EndOfFile)
        {
              _gameServerType = GameServerType(int(recordsetPtr->Fields->Item["GameServerType_ID"]->Value));
              recordsetPtr->Close();
        }
   
        recordsetPtr->Release();
  }
   
  Player::~Player()
  {
  }

I’m getting:

Error      1              error LNK2019: unresolved external symbol _gethostname@8 referenced in function "private: char * __thiscall Player::GetHostname(void)" (?GetHostname@Player@@AAEPADXZ)               Player.obj

How do I properly link to winsock.h?

You need to link the lib file. winsock32.lib maybe?
But please remember that you are completely removing linux compatibility, unless you can find a nix' equivalent and use #ifdef's

For winsock2

Aha!

Ws2_32.lib

Good luck. Remember, you are going to need that Linux equivalent if you don't want to break nix support.

Linux is overrated, real server ops run Windows so they can be TCAdmin Guinea Pigs!

Looks like a possible linux equivalent, not sure it is returning the same thing that the windows version is though.

Thanks Mani,
I found that page, that’s where I got my sample code from.

Thanks PimpinJuice,
That’s the piece I was missing.
