Line buffering does not work in Win32 version.

[turtle]

Hi all,

There seems to be a bug in the line buffering of TCP sockets when using the
Win32 version of GProlog. Look at this example code:

% Define socket
socket('AF_INET', Socket),
% Try to connect
socket_connect(Socket, 'AF_INET'(localhost, 40000), In, Out),
% Put the buffering to line-based
set_stream_buffering(Out, line),
% Write something to the socket
write(Out, 'Hello'), nl(Out), read_token(In, _).

=====================

This works perfect in Linux. However, when using the Win32 version of GProlog,
the 'other side' keeps waiting for a CR after the 'Hello' is sent, in spite of
the "nl(Out)".

This was my test environment:

Gnu Prolog 1.2.16 compiled on Slackware 9.1 kernel 2.4.22
Gnu Prolog 1.2.16 used on Windows2000 SP 1.

Regards

Peter.
