Description
bool
pcntl_setpriority ( int priority [, int pid])
pcntl_setpriority() sets the priority of
pid to priority. If
pid is not specified, the pid of the current
process is used.
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.
Returns TRUE on success or FALSE on failure.
