NICE(3)			   BSD Programmer's Manual		       NICE(3)

NAME
     nice - change process scheduling priority

SYNOPSIS
     #include <unistd.h>

     int
     nice(int incr);

DESCRIPTION
     This interface is obsoleted by setpriority(2).

     The nice() function adds the value specified in incr to the scheduling
     priority of the invoking process.

     incr is an integer such that the resulting scheduling priority is within
     the range -20 to 20. Priority values outside this range are truncated to
     the appropriate limit. The default priority is 0; lower priorities cause
     more favorable scheduling. Only the superuser may lower priorities.

     Children inherit the priority of their parent processes via fork(2).

RETURN VALUES
     On success, nice() returns the new priority. On error, it returns -1.

     Since nice() can legitimately return the value -1, it is necessary to
     clear the external variable errno prior to the call, then check it after-
     ward to determine if a -1 is an error or a legitimate value.

ERRORS
     nice() has the same failure conditions as setpriority(2).

SEE ALSO
     nice(1), fork(2), setpriority(2), renice(8)

HISTORY
     A nice() system call appeared in Version 6 AT&T UNIX.
