我使用從MSDN的源代碼，C++的Winsock服務器&客戶端，在服務器端，我將大部分函數的代碼時遇到一個訪問衝突錯誤。我的完整源代碼如下。C++的Winsock應用程序訪問衝突
任何幫助將是偉大的，在此先感謝！ 這是我j420s，CPP文件。

Here is my j420s.h file.

int SocketInit(int, WSADATA*);
int SocketAddrInfo(int, addrinfo*, addrinfo*);
SOCKET SocketCreate(SOCKET, addrinfo*);
int SocketBind(int, SOCKET, addrinfo*);
int SocketListen(int, SOCKET, addrinfo*);
SOCKET SocketAcceptConnection(SOCKET, SOCKET);
訪問衝突是介於此功能：
int SocketAddrInfo(int iResult, addrinfo* MySocket, addrinfo* MySocketResult){
iResult = getaddrinfo(NULL, DEFAULT_PORT, MySocket, &MySocketResult);
if (iResult != 0) {
printf("getaddrinfo failed with error: %d\n", iResult);
WSACleanup();
return 1;
}
return iResult;
}
我調用該函數像這樣：
iResult = SocketAddrInfo(iResult, &MySocket, MySocketResult);
我相信這件事情與我的指針...
同樣，任何幫助將是巨大的！再次感謝！
「訪問衝突則介於此功能」 這是確定嗎？這是用調試器還是其他方法證實的？ – MikeCAT
