[Lua][Question] How to suck a specified number of items out of a chest?

Title: "[Lua][Question] How to suck a specified number of items out of a chest?

Title sums it up really, but I was wondering if there was a way to pull a certain number of items out if a chest. For example I was trying to use turtle.suck(4), however this pulls out as many as it can from the first slot,
Is this supposed to happen or is it a bug?
Also any differant idea's on how to do this?
Thanks

This is not a bug, however, I believe the mod MiscPeripherals by RichardG allows more in depth "inventory management" methods

Ah, got it. I'll have a look into it but this seams to be able to do waht I want.
Thanks :D/>

Also you could do this.

turtle.suck() -- gets all items
local wanted = 24
local actuallyGot = turtle.getItemCount( 1 ) -- where one is the slot we just sucked into
if actuallyGot - wanted == 0 then
  print("We got the perfect amount")
elseif actuallyGot - wanted > 0 then
  turtle.drop( actuallyGot - wanted ) -- drop off the excess
else
  print("We didn't get as many as we wanted :(/>")
end
