nice
nice(2) System Calls nice(2)NAME
nice - change priority of a process
SYNOPSIS
#include <unistd.h>
int nice(int incr);
DESCRIPTION
The nice() function allows a process to change its priority. The invoking process must be in a scheduling class that supports the nice().
The nice() function adds the value of incr to the nice value of the calling process. A process's nice value is a non-negative number for
which a greater positive value results in lower CPU priority.
A maximum nice value of (2 * NZERO) -1 and a minimum nice value of 0 are imposed by the system. NZERO is defined in <limits.h> with a
default value of 20. Requests for values above or below these limits result in the nice value being set to the corresponding limit. A nice
value of 40 is treated as 39.
Calling the nice() function has no effect on the priority of processes or threads with policy SCHED_FIFO or SCHED_RR.
Only a process with the {PRIV_PROC_PRIOCNTL} privilege can lower the nice value.
RETURN VALUES
Upon successful completion, nice() returns the new nice value minus NZERO. Otherwise, -1 is returned, the process's nice value is not
changed, and errno is set to indicate the error.
ERRORS
The nice() function will fail if:
EINVAL The nice() function is called by a process in a scheduling class other than time-sharing or fixed-priority.
EPERM The incr argument is negative or greater than 40 and the {PRIV_PROC_PRIOCNTL} privilege is not asserted in the effective set of
the calling process.
USAGE
The priocntl(2) function is a more general interface to scheduler functions.
Since -1 is a permissible return value in a successful situation, an application wishing to check for error situations should set errno to
0, then call nice(), and if it returns -1, check to see if errno is non-zero.
