module Cpu_use: sig .. end
A module for getting a process's CPU use.
type
get returns a Cpu_use.t for the given pid or the current processes's pid, if none
given. Note that the cpu_use given by this initial value will probably be
invalid.
val get : ?pid:Core.Std.Pid.t -> unit -> t
update_exn updates a Cpu_use.t. It will fail if the process no longer exists.
val update_exn : t -> unit
cpu_use gives an estimated CPU usage (between 0 and 1) in the time period between
the last 2 calls to update_exn.
val cpu_use : t -> float
