note 83201 added to function.pcntl-getpriority

This function is ideal for checking if a given process is running, I have seen solutions that involve running the system utilites like PS and parsing the answer, which should work fine, but this allows you to check a given PID with a single call function CheckPID( $PID ) { // Check if the passed in PID represents a vlaid process in the system // Returns true if it does // Turn off non-fatal runtime warning for a moment as we know we // will get one if the PID does not represent a valid process $oldErrorLevel = error_reporting(0); error_reporting( $oldErrorLevel & ~E_WARNING ); $res = pcntl_getpriority($PID); error_reporting( $oldErrorLevel); return ! ( $res === false); } ---- Server IP: 87.124.64.96 Probable Submitter: 80.177.197.163 ---- Manual Page -- http://www.php.net/manual/en/function.pcntl-getpriority.php Edit -- https://master.php.net/note/edit/83201 Del: integrated -- https://master.php.net/note/delete/83201/integrated Del: useless -- https://master.php.net/note/delete/83201/useless Del: bad code -- https://master.php.net/note/delete/83201/bad+code Del: spam -- https://master.php.net/note/delete/83201/spam Del: non-english -- https://master.php.net/note/delete/83201/non-english Del: in docs -- https://master.php.net/note/delete/83201/in+docs Del: other reasons-- https://master.php.net/note/delete/83201 Reject -- https://master.php.net/note/reject/83201 Search -- https://master.php.net/manage/user-notes.php
