nice
— set program
scheduling priority
Standard C Library (libc, -lc)
#include
<unistd.h>
int
nice
(int
incr);
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).
A nice
() syscall appeared in
Version 6 AT&T UNIX.
