22 /* This file is supposed to be used on platforms that lack
23 sys/socket.h. It is intended to provide definitions and prototypes
24 needed by an application.
26 Currently only MinGW is supported. See the gnulib manual regarding
27 Windows sockets. MinGW has the header files winsock2.h and
28 ws2tcpip.h that declare the sys/socket.h definitions we need. Note
29 that you can influence which definitions you get by setting the
30 WINVER symbol before including these two files. For example,
31 getaddrinfo is only available if _WIN32_WINNT >= 0x0501 (that
32 symbol is set indiriectly through WINVER). You can set this by
33 adding AC_DEFINE(WINVER, 0x0501) to configure.ac. Note that your
34 code may not run on older Windows releases then. My Windows 2000
35 box was not able to run the code, for example. The situation is
36 slightly confusing because:
37 http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winsock/winsock/getaddrinfo_2.asp
38 suggests that getaddrinfo should be available on all Windows
