_/proc/stat vs /proc/uptime

Hi,

I am trying to calculate the CPU Usage by getting the difference between the idle time reported by /proc/stat at 2 different intervals. Now the 4th entry in the first line of /proc/stat will give me the 'idle time'. But I also came across /proc/uptime that gives me 2 entries : 1st one as the time in seconds since the system has been 'up' and the other entry being the number of seconds the system has been idle.

Dummy question : Should the 4th entry the /proc/stat and the 2nd entry /proc/uptime match each other ? If not, why ?

Thanks

__________________________________________________________________________________________________________________________________________________

NAME
Tcl_CreateCloseHandler, Tcl_DeleteCloseHandler - arrange for callbacks when channels are closed SYNOPSIS
#include <tcl.h> void Tcl_CreateCloseHandler(channel, proc, clientData) void Tcl_DeleteCloseHandler(channel, proc, clientData) ARGUMENTS
Tcl_Channel channel (in) The channel for which to create or delete a close callback. Tcl_CloseProc *proc (in) The procedure to call as the callback. ClientData clientData (in) Arbitrary one-word value to pass to proc. _________________________________________________________________ DESCRIPTION
Tcl_CreateCloseHandler arranges for proc to be called when channel is closed with Tcl_Close or Tcl_UnregisterChannel, or using the Tcl close command. Proc should match the following prototype: typedef void Tcl_CloseProc( ClientData clientData); The clientData is the same as the value provided in the call to Tcl_CreateCloseHandler. Tcl_DeleteCloseHandler removes a close callback for channel. The proc and clientData identify which close callback to remove; Tcl_Delete- CloseHandler does nothing if its proc and clientData arguments do not match the proc and clientData for a close handler for channel.
