Hi.

Can anyone with windows knowledge take a quick look at
http://bugs.php.net/bug.php?id=47918. I'm pretty sure this IS a bug.
I'm hoping you don't say it is a documentation bug and it is something
you can fix.

My requirement is to allow non-blocking file i/o.

With non-win32, it seems that the fcntl() function can accept
O_NONBLOCK. This does not seem to be present on win32.


The doc for `fopen()` does not mention 'n' as being available (probably
for this reason).


Regards,

Richard.

fcntl() is not available on Windows aswell as O_NONBLOCK, but after
some small research we could perhaps use the iocsocket() function with
the FIONBIO flag to emulate O_NONBLOCK on Windows.

The 'n' mode was added in 5.3 RC2 by Mikko, but has not yet been documented.
