| One of the portability problems for native Windows are sockets and |
| networking functions. |
| |
| @subsection Getaddrinfo and WINVER |
| |
| This was written for the @code{getaddrinfo} module, but may be applicable to |
| other functions too. |
| |
| The @code{getaddrinfo} function exists in @code{ws2tcpip.h} and @code{-lws2_32} |
| on Windows XP. The function declaration is present if @code{WINVER >= 0x0501}. |
| Windows 2000 does not have @code{getaddrinfo} in its @file{WS2_32.DLL}. |
| |
| Thus, if you want to assume Windows XP or later, you can add |
| @code{AC_DEFINE([WINVER], [0x0501])} to avoid compiling the (partial) |
| @code{getaddrinfo} implementation. |
| |
| If you want to support Windows 2000, don't do anything. The |
| replacement function will open @file{WS2_32.DLL} during run-time to |
| see if there is a @code{getaddrinfo} function available, and use it when |
| available. |
