nice3
Set program scheduling priority
Usage
#include <unistd.h>
int
nice(int incr);
Library
Standard C Library (libc, -lc)
Overview
This interface is obsoleted by setpriority(2).
The nice() function obtains the scheduling priority of the process from the system and sets it to the priority value specified in incr. The priority is a value in the range -20 to 20. The default priority is 0; lower priorities cause more favorable scheduling. Only the super-user may lower priorities.
Children inherit the priority of their parent processes via fork(2).
