NICE(II) 3/15/72 NICE(II) NAME nice - set program priority SYNOPSIS (nice = 34.) (priority in r0) sys nice nice(priority) DESCRIPTION The currently executing process is set into the priority specified by priority. If priority is positive, the priority of the process is below default; if negative the process must be the super-user and its priority is raised. The valid range of priority is 20 and -220. The value of 16 is recommended to users who wish to execute long-running programs without flak from the administration. The effect of this call is passed to a child process by the fork system call. The effect can be cancelled by another call to nice with a priority of 0. SEE ALSO nice(I) DIAGNOSTICS The error bit (c-bit) is set if the user requests a priority outside the range of 0 to 20 and is not the super-user.
