 * versions of Windows, then you need to include the Ws2tcpip.h and
 * Wspiapi.h files. When the Wspiapi.h include file is added, the
 * getaddrinfo function is defined to the WspiapiGetAddrInfo inline
 * function in the Wspiapi.h file. At runtime, the WspiapiGetAddrInfo
 * function is implemented in such a way that if the Ws2_32.dll or the
 * Wship6.dll (the file containing getaddrinfo in the IPv6 Technology
 * Preview for Windows 2000) does not include getaddrinfo, then a
 * version of getaddrinfo is implemented inline based on code in the
 * Wspiapi.h header file. This inline code will be used on older Windows
 * platforms that do not natively support the getaddrinfo function."
 *
