NICE(3)                                 BSD Library Functions Manual                                 NICE(3)

NAME
     nice -- set program scheduling priority

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <unistd.h>

     int
     nice(int incr);

DESCRIPTION
     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 prior-ity priority
     ity 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).
