@section Windows sockets
|
|
|
|
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.
