pcntl_setpriority — Change the priority of any process
$priority
[, int $pid = getmypid()
[, int $process_identifier = PRIO_PROCESS
]] ) : bool
pcntl_setpriority() sets the priority of
pid.
priority
priority is generally a value in the range
-20 to 20. The default priority
is 0 while a lower numerical value causes more
favorable scheduling. Because priority levels can differ between
system types and kernel versions, please see your system's setpriority(2)
man page for specific details.
pidIf not specified, the pid of the current process is used.
process_identifier
One of PRIO_PGRP, PRIO_USER
or PRIO_PROCESS.
