NICE(3)			 BSD Library Functions Manual		       NICE(3)

NAME
     nice — set program scheduling priority

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <unistd.h>

     int
     nice(int incr);

DESCRIPTION
     This interface is obsoleted by setpriority(2).

     The nice() function obtains the scheduling priority of the process from
     the system and sets it to the priority value specified in incr.  The pri‐
     ority 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).

RETURN VALUES
     Upon successful completion, nice() returns the new nice value.  Other‐
     wise, -1 is returned, the process' nice value is not changed, and errno
     is set appropriately.

ERRORS
     The nice() function will fail if:

     [EPERM]		The incr argument is negative and the calling process
			does not have super-user privileges.

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

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