pcntl_setpriority — Change the priority of any process
$priority, ?int $process_id = null, int $mode = PRIO_PROCESS): bool
pcntl_setpriority() sets the priority of
process_id.
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.
process_id
If null, the process id of the current process is used.
mode
One of PRIO_PGRP, PRIO_USER,
PRIO_PROCESS,
PRIO_DARWIN_BG or PRIO_DARWIN_THREAD.
Returns true on success or false on failure.
