nice(2) System Calls Manual nice(2)
NAME
nice - change priority of a process
SYNOPSIS
DESCRIPTION
adds the value of priority_change to the nice value of the calling process. A process's is a positive number for which a more positive
value results in lower CPU priority.
A maximum nice value of 39 and a minimum nice value of 0 are imposed by the system. Requests for values above or below these limits result
in the nice value being set to the corresponding limit.
If the calling process contains more than one thread or lightweight process (i.e., the process is multi-threaded) this function shall apply
to all threads or lightweight processes in the calling process.
Security Restrictions
Some or all of the actions associated with this system call are subject to compartmental restrictions. See compartments(5) for more infor-
mation about compartmentalization on systems that support that feature. Compartmental restrictions can be overridden if the process pos-
sesses the privilege (COMMALLOWED). Processes owned by the superuser may not have this privilege. Processes owned by any user may have
this privilege, depending on system configuration.
Some or all of the actions associated with this system call require the (OWNER) and/or the (LIMIT) privileges. Processes owned by the
superuser will have these privileges. Processes owned by other users may have privilege(s), depending on system configuration. See privi-
leges(5) for more information about privileged access on systems that support fine-grained privileges.
RETURN VALUE
Upon successful completion, returns the new nice value minus 20. Otherwise, a value of -1 is returned and is set to indicate the error.
Note that assumes a user process priority value of 20. If a user having appropriate privileges has changed the user process priority value
to something less than 20, certain values for priority_change can cause to return -1, which is indistinguishable from an error return.
ERRORS
[EPERM] fails and does not change the nice value if priority_change is negative or greater than 40, and the effective user ID of the
calling process is not a user having appropriate privileges.
