It is easy now to change the places where errno is
checked to the appropriate wrapper (my_socket_would_block,
I'm not sure about the places EINTR is checked for,
is it really ok to ignore that error? (If yes I suppose
my_socket_operation_was_interrupted or some such should
As for checking errno for printing an appropriate message
mystrerror should be used, or a similar translation
function (that would do the right thing depending on
I think wrapper functions would be a better approach
than besprinkling the code with #ifdefs, of course you
maintainers know best :).
Actually we did all this for warclient already when
I wrote an asynchronous (i.e. non-blocking) network
system (as proof of concept I made downloading the
metaserver list asynchronous in the client - it is
in the warclient 2.0 unstable branch). The problem
was that the giochannel implementation on win32
was flaky. Yaro made a patch for glib which seemed
to fix the problem (submitted to gnome bugtracker
http://bugzilla.gnome.org/show_bug.cgi?id=357674) but it
has not been processed yet. Rather than forcing people
on win32 to use our patched glib we decided to hold off
rewriting more of the annoying blocking network code (e.g.
metaserver send/recv) in wait of a better solution. :/
