note 79948 added to function.pcntl-signal

Multiple children return less than the number of children exiting at a given moment SIGCHLD signals is normal behavior for Unix (POSIX) systems. SIGCHLD might be read as "one or more children changed status -- go examine your children and harvest their status values". Signals are implemented as bit masks in most Unix systems, so there can only be 1 SIGCHLD bit set in any given kernel tick for a process. ---- Server IP: 217.13.201.10 Probable Submitter: 87.139.65.181 ---- Manual Page -- http://www.php.net/manual/en/function.pcntl-signal.php Edit -- https://master.php.net/note/edit/79948 Del: integrated -- https://master.php.net/note/delete/79948/integrated Del: useless -- https://master.php.net/note/delete/79948/useless Del: bad code -- https://master.php.net/note/delete/79948/bad+code Del: spam -- https://master.php.net/note/delete/79948/spam Del: non-english -- https://master.php.net/note/delete/79948/non-english Del: in docs -- https://master.php.net/note/delete/79948/in+docs Del: other reasons-- https://master.php.net/note/delete/79948 Reject -- https://master.php.net/note/reject/79948 Search -- https://master.php.net/manage/user-notes.php
