获取本地计算机的IP地址

关键点

WSAStartup

The Windows Sockets WSAStartup function initiates use of Ws2_32.dll by a process.

int WSAStartup(

WORDwVersionRequested,

LPWSADATAlpWSAData

);

实现过程

#include <winsock2.h>

#pragma comment(lib, "ws2_32.lib")

char* GetIpAddress()

{

WSADATA wsadata;

WSAStartup(MAKEWORD(2, 2), &wsadata);

char szHostName[MAX_PATH + 1];

gethostname(szHostName, MAX_PATH);

hostent *p = gethostbyname(szHostName);

return inet_ntoa(*(in_addr *)p->h_addr_list[0]);

}

MessageBox(GetIpAddress());

备注

//szHostName 就是计算机的名子
