pcntl_getpriority() gets the priority of
pid
. If pid
is not
specified, the pid of the current process is used. Because priority
levels can differ between system types and kernel versions, please see
your system's getpriority(2) man page for specific details.
pcntl_getpriority() returns the priority of the process or FALSE on error. A lower numerical value causes more favorable scheduling.
process_identifier
is one of
PRIO_PGRP,
PRIO_USER or
PRIO_PROCESS.
Warning |
This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE, such as 0 or "". Please read the section on Booleans for more information. Use the === operator for testing the return value of this function. |
