C/C++ 通过域名取IP

char* GetIP(char* chName/*这个是域名*/)

{

hostent* host = gethostbyname(chName);

host->h_addr_list;

char chIp[32];

sprintf(chIp, "%d.%d.%d.%d",

host->h_addr_list[0][0] & 0x00ff,

host->h_addr_list[0][1] & 0x00ff,

host->h_addr_list[0][2] & 0x00ff,

host->h_addr_list[0][3] & 0x00ff);

return chIp;//返回IP

}

要2个头文件:windows.h stdio.h,上次发现Socket不能直接连接域名的....要转化成IP才可以
