NAME

nice - change process priority  

SYNOPSIS

#include <unistd.h>

int nice(int inc);  

DESCRIPTION

nice adds inc to the priority for the calling pid. Note that only the superuser may specify a negative increment, or priority increase. Note that internally, a higher number is a higher priority. Do not confuse this with the priority scheme as used by the nice interface.  

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, a numerical decrease, by supplying a negative inc.
