les erreurs de socket ne peuvent pas obtenir de fonctions dans WinSock2.h
J'ai créé une classe de wrapper de socket, mais j'ai trop d'erreurs que je ne sais pas comment résoudre. J'ai essayé Erreur du didacticiel Winsock et Impossible d'inclure Winsock2.h dans MSVC 2010 , mais aucune utilisation
Voici le code:
//#define WIN32_LEAN_AND_MEAN
#include <iostream>
#include <string>
#include <Windows.h>
#include <WinSock2.h>
#include <WS2tcpip.h>
#pragma comment(lib,"ws2_32_lib")
using namespace std;
#define WM_SOCKET 0x10000
class Socket
{
};
Voici les erreurs:

Vous devez ré-ordonner les includes des en-têtes Windows comme ceci:
#include <WinSock2.h>
#include <WS2tcpip.h>
#include <Windows.h>
En d'autres termes, les en-têtes WinSock doivent être inclus avant Windows.h.
Ou définissez WIN32_LEAN_AND_MEAN que vous avez commenté pour une raison quelconque.
Je pense que vous devrez également changer la méthode Accept pour renvoyer SOCKET au lieu de Socket.
Et le #pragma devrait être:
#pragma comment(lib,"ws2_32")
Je me suis assuré que #include "Winsock2.h" était avant tout #include "windows.h" et "#include" Winsock.h "et que l'affaire était résolue.
Juste une question de patience, regardez un par un et établissez cet ordre, d'abord #include "Winsock2.h" puis #include "windows.h"
J'ai vérifié les inclusions récursives, j'ai repéré les fichiers d'en-tête qui incluent (récursivement) des #include "windows.h" et "#include" Winsock.h et écris un # include "Winsock2.h". J'ai ajouté dans ce fichier #include "Winsock2.h" `en tant que première inclusion.
Vous ne pouvez pas inclure Windows.h avant d'inclure WinSock2, car cela entraînerait l'en-tête de Windows pour inclure une version plus ancienne de winsock. Supprimez le Windows.h inclure tout à fait.
Voir, par exemple, ce lien MSDN: http://msdn.Microsoft.com/en-us/library/windows/desktop/ms737629(v=vs.85).aspx La note la partie sous le premier bloc de code explique cela.
