106 * "Support for getaddrinfo on Windows 2000 and older versions
107 * The getaddrinfo function was added to the Ws2_32.dll on Windows XP and
108 * later. To execute an application that uses this function on earlier
109 * versions of Windows, then you need to include the Ws2tcpip.h and
110 * Wspiapi.h files. When the Wspiapi.h include file is added, the
111 * getaddrinfo function is defined to the WspiapiGetAddrInfo inline
112 * function in the Wspiapi.h file. At runtime, the WspiapiGetAddrInfo
113 * function is implemented in such a way that if the Ws2_32.dll or the
114 * Wship6.dll (the file containing getaddrinfo in the IPv6 Technology
115 * Preview for Windows 2000) does not include getaddrinfo, then a
116 * version of getaddrinfo is implemented inline based on code in the
117 * Wspiapi.h header file. This inline code will be used on older Windows
118 * platforms that do not natively support the getaddrinfo function."
120 * We use getaddrinfo(), so we include Wspiapi.h here. pcap-stdinc.h
121 * includes Ws2tcpip.h, so we don't need to include it ourselves.
