C:UsersChanDesktoptest - failwinsock2 socket server.cpp: In function `int _tmain()':
C:UsersChanDesktoptest - failwinsock2 socket server.cpp:48: error: `getaddrinfo' was not declared in this scope
C:UsersChanDesktoptest - failwinsock2 socket server.cpp:59: error: `freeaddrinfo' was not declared in this scope

C:UsersChanDesktoptest - failwinsock2 socket server.cpp:74: error: `freeaddrinfo' was not declared in this scope

使用此头文件

#include "winsock2.h"
#include "windows.h"
#include "WS2tcpip.h"

头文件 WS2tcpip.h 使用这个定义：

#if (_WIN32_WINNT >= 0x0600)

这意味着在构建中，应将_WIN32_WINNT定义为 0x600 (Vista( 或更高版本。这意味着您想要的 API 在 WinXP 中不存在。
