unfortunatley that failed as well ... here is a simple example:

<?php
 stream_set_timeout(STDIN, 3);
 $in = fgets(STDIN);
 echo $in;
?>

i was expecting this to bail out and print nothing after 3 seconds ...

Jon,

I remembered seeing something about stream timeouts at
php.net 

I was curious so I looked it up:

bool stream_set_timeout ( resource stream, int seconds [,
int microseconds])


Sets the timeout value on stream, expressed in the sum of
seconds and microseconds. 


Note: As of PHP 4.3, this function can (potentially) work on
any kind of stream. In PHP 4.3, socket based streams are
still the only kind supported in the PHP core, although
streams from other extensions may support this function. 

I don't know if this is any help -- but it might be.

ok after further investigation i realized i should have
worded my question
differently but in a nutshell:

this requires process control functions for setting a
timeout to not wait
for STDIN (otherwise user needs to type something first) in
turn these
functions are not available on Windoze.  so just to clarify
my question -
"on W32 there is no way to timeout STDIN from cli?"
