VC升级VS2013 关于gethostbyname的问题

[xiaodeerdeer]

warning C4996: 'gethostbyname': Use getaddrinfo() or GetAddrInfoW() instead or define _WINSOCK_DEPRECATED_NO_WARNINGS to disable deprecated API

源代码如下

a.sock = socket( AF_INET, SOCK_STREAM, 0);
if (a.sock == INVALID_SOCKET) {
return -1;
}
else {
b.sin_family = AF_INET;
if ((phe = gethostbyname(PIPAddr)) == NULL) {
return -2;
}
else {
memcpy((char FAR *)&(b.sin_addr), phe->h_addr, phe->h_length);
。。。
如何将gethostbyname换成getaddrinfo或者是GetAddrInfoW，最好把代码贴出来，还请各位大神帮忙解决，小弟在此感激不尽。

感谢两位的回复，我想再不改原来的逻辑基础上进行修改 只是想把gethostbyname换掉，但是不知道怎么改，还请两位帮忙解决一下 谢谢
