NAMEnice — set program scheduling priority
LIBRARYStandard C Library (libc, -lc)
SYNOPSIS#include < unistd.h>
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).
HISTORYA nice() syscall appeared in Version 6 AT&T UNIX.
