谁能提供给小弟获取本机ip地址，机器名，登陆的用户名的函数啊？好用就给分

[feigner]

本人需要能获取本机IP地址，机器名，登陆的用户名的函数，希望大虾们踊跃发言，帮帮小弟吧！只要函数管用就给分，好的话再追加分数

/*
函数：取得用户名

void CSystemInfo::GetUser()
{
TCHAR computerbuf[256];
DWORD computersize=256;
memset(computerbuf,0,256);
if(!GetComputerName(computerbuf,&computersize))
return;
computerbuf[computersize]=0;

///////get user name/////////
TCHAR userbuf[256];
DWORD usersize=256;

if(!GetUserName(userbuf,&usersize))
return;
userbuf[usersize]=0;
strcpy(user,userbuf);
strcat(user," / ");
strcat(user,computerbuf);
}

/*

CString CSystemInfo::GetLocalIP()
{

CString m_addr;

}
return sNetBiosName;

错了错了，这是罗列局蜮网内的机器IP和名字。而且汉字成乱吗了，再贴

[tangshiping]

WORD wVersionRequested;
WSADATA wsaData;
char name[255];
CString ip;
PHOSTENT hostinfo;
wVersionRequested = MAKEWORD( 2, 0 );

if ( WSAStartup( wVersionRequested, &wsaData ) == 0 )
{

if( gethostname ( name, sizeof(name)) == 0)
{
if((hostinfo = gethostbyname(name)) != NULL)
{
ip = inet_ntoa (*(struct in_addr *)*hostinfo->h_addr_list);
}
}

WSACleanup( );
}
// AfxMessageBox(name);//Name

同意一楼的。

GetUserName()，用户名
GetComputerName(),机器名
gethostname(),ip地址
