note 47166 added to function.usleep

usleep() in windows using PHP 5.0.2 It seems that usleep() in this config has a minimum sleep time of around 10 milliseconds. Thats 10,000 microseconds. ie: <? set_time_limit(10); while(1) { echo "."; usleep(1); ob_flush(); } ?> On windows this only results in about a thousand periods being displayed before the timelimit kills the script. The CPU use is not hit at all. On any other platform this would try to send almost 10 billion periods and probably take a CPU hit in the process ;-) This is worlds better than sleep(), but still doesn't hold a candle to usleep() on other platforms. ---- Manual Page -- http://www.php.net/manual/en/function.usleep.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+47166 Delete -- http://master.php.net/manage/user-notes.php?action=delete+47166&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+47166&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+47166&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+47166&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+47166&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+47166&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+47166&report=yes Search -- http://master.php.net/manage/user-notes.php
