NICE(2) Linux Programmer's Manual NICE(2)
NAME
nice - change process priority
SYNOPSIS
#include <unistd.h>
int nice(int inc);
DESCRIPTION
nice adds inc to the nice value for the calling pid. (A large nice value means a low priority.) Only the superuser may specify a negative
increment, or priority increase.
RETURN VALUE
On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
ERRORS
EPERM A non-super user attempts to do a priority increase by supplying a negative inc.
CONFORMING TO
SVr4, SVID EXT, AT&T, X/OPEN, BSD 4.3. However, the Linux and glibc (earlier than glibc 2.2.4) return value is nonstandard, see below.
SVr4 documents an additional EINVAL error code.
NOTES
Note that the routine is documented in SUSv2 to return the new nice value, while the Linux syscall and (g)libc (earlier than glibc 2.2.4)
routines return 0 on success. The new nice value can be found using getpriority(2). Note that an implementation in which nice returns the
new nice value can legitimately return -1. To reliably detect an error, set errno to 0 before the call, and check its value when nice
returns -1.
