MFC获取本机IP的方法

工作中遇到需要sip发送REGISTER时，参数需要程序自动获取本机ip 实现如下：这些只是核心代码///

      #include <winsock.h>

      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(ip); //返回CString类型的，根据需要自己调整
