wine users - Feb 2008 - fflush now?

The stdio buffers (stdout, stderr) do not seem to flush until my wine
app exists.

I was testing pipes between PHP http://php.net/proc_open and Wine on
version 0.9.42 then the current 0.9.55 and only when I was returning
from my wine app, would the buffers flush.  In a real case, I do not
return from the wine app that quickly, but never see the data in the
stream unless I explicitly return from the wine app with a return
statement or kill the wine app and return from the app's WinMain.

This seems to have been a bug in the past
http://www.winehq.org/pipermail/wine-cvs/2006-March/021782.html Has it
returned?  I believe I found a page yesterday mentioning flush and app
exit with Alexandre Julliard, but this isn't the one
http://www.winehq.org/pipermail/wine-patches/2005-May/017363.html

I recall running a wine-0.9.27 or later and fflush worked (not using pipes).

If you try it from PHP, the $descriptorspec should be = array(
   0 => array("pipe", "r"),
   1 => array("pipe", "w"),
   2 => array("pipe", "w")
);

("w", not "r" for stderr, index 2).

Does wine fflush when you tell it?

Code compiled in VC++6.0 on MS Win XP; Run on Mac OSX Tiger Intel.
fflush(stdout);
fflush(stderr);

Regards.

Apparently a PHP problem
http://php.net/manual/en/function.stream-get-contents.php#69229
"the "max length" parameter seems to act more as an exact length
parameter, as the stream will block indefinitely until max length is
reached"

fclose on the "other side", which in this case was wine, didn't
work.
But now I can move on.

Thanks to all who commented.
