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 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).
SEE ALSO nice(1), fork(2), setpriority(2), renice(8)HISTORY
A nice() syscall appeared in Version 6 AT&T UNIX.
BSD June 4, 1993 BSD

nice - set program priority
Syntax
int nice(incr)
int incr;
Description
The scheduling priority of the process is augmented by incr. Positive priorities get less service than normal. Priority 10 is recommended
to users who wish to execute long-running programs without flack from the administration.
Negative increments are ignored except on behalf of the super-user. The priority is limited to the range -20 (most urgent) to 20 (least).
The priority of a process is passed to a child process by For a privileged process to return to normal priority from an unknown state,
should be called successively with arguments -40 (goes to priority -20 because of truncation), 20 (to get to 0), then 0 (to maintain com-
patibility with previous versions of this call).
Environment
In any mode, nice returns -1 and sets on an error. On success, the return value depends on the mode in which your program was compiled.
In POSIX or System V mode, it is the new priority; otherwise, it is zero. Note that, in POSIX and System V mode, -1 can indicate either
success or failure; must be used to determine which.
