本文主要向大家介绍了VC编程获取本地IP和机器名，通过具体的内容向大家展示，希望对大家学习VC编程有所帮助。

#include <winsock2.h>

#include <string>

#include <boost/filesystem.hpp>

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

std::string GetLocalIpAndSave(void)

{

WSADATA wsaData;

char name[155];

std::string strIp;

PHOSTENT hostinfo;

if ( WSAStartup( MAKEWORD(2,0), &wsaData ) == 0 ) {

if( gethostname ( name, sizeof(name)) == 0) {     //获取机器名

if((hostinfo = gethostbyname(name)) != NULL) { //这些就是获得IP的函数

strIp = inet_ntoa (*(struct in_addr *)*hostinfo->h_addr_list); //获取本机ip

}

}

WSACleanup( );

}

CHAR path[MAX_PATH] = {0};

GetModuleFileNameA(NULL, path, MAX_PATH);

boost::filesystem::path fpath(path);

fpath = fpath.parent_path();

fpath /= "serverip.txt";

FILE* f = fopen(fpath.string().c_str(), "wb+");

fwrite(PVOID(strIp.c_str()), strIp.size(), 1, f);

fclose(f);

return strIp;//返回本机ip

}
