C++高手请进

恩,怎么样写一个函数来获取本地的IP地址,并且保存下来呢,谢拉

..这个用得着C++么...一支笔不就够了

如果你要的话给你参考一下吧:

#include

using std::cin;

using std::cout;

using std::cerr;

using std::endl;

#include

using std::list;

#include

using std::string;

#include

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

bool GetIpList( list r_iplist )

{

WORD wVersionRequested;

WSADATA wsaData;

int err;

wVersionRequested = MAKEWORD( 2, 2 );

err = WSAStartup( wVersionRequested, &wsaData );

if ( err != 0 )

{

cout < < "WSAStartup failed !" < < endl;

return false;

}

char szhn[256];

int nStatus = gethostname(szhn, sizeof(szhn));

if (nStatus == SOCKET_ERROR )

{

cout < < "gethostname failed, Error code: " < < WSAGetLastError() < < endl;

return false;

}

HOSTENT *host = gethostbyname(szhn);

if (host != NULL)

{

for ( int i=0; ; i++ )

{

r_iplist.push_back( inet_ntoa( *(IN_ADDR*)host-> h_addr_list[i] ) ) ;

if ( host-> h_addr_list[i] + host-> h_length > = host-> h_name )

break;

}

}

WSACleanup();

return true;

}

int main(int argc, char *argv[])

{

list iplist;

std::list ::iterator ip;

if ( !GetIpList( iplist ) )

{

cout < < "Get ip list failed !" < < endl;

return -1;

}

cout < < "IP list :" < < endl;

for ( ip = iplist.begin(); ip != iplist.end(); ip++ )

{

cout < < " " < < *ip < < endl;

}

return 0;

}
