Getting function instead of table

Hello everyone,
First i need to mention that i'm new to computercraft also to programming and sorry if this problems seems a bit silly.
I'm trying to create a monitor that manages my storage on minecraft. I'm using openPeripherals on JABBA Barrels the problem is whenever i use the getStoredItems function it returns a function instead of a table i've been searching for hours now and it really buggs me , thanks for help <3

local brl = peripheral.wrap("top")
local infbrl = brl.getStoredItems
for k,v in pairs(infbrl) do
print(k.." = "..v)
end

You have to actually call the function.

local infbrl = brl.getStoredItems()

Notice the parentheses.

Thanks a lot , i figured it out yet is there a documentation for Openperipherals events ? I'm sort of trying to make my program dynamic ==> whenever i pull items from the barrel the monitor screen changes, again thanks a lot!

No, I don't believe there's any documentation for the events you might get back from OpenPeripheral peripherals. You might try running a loop like this:

while true do print(os.pullEvent()) end

… then messing with your peripheral to see if you can trigger any lines of text.

Well sadly the peripherals seem only to pull an attach or detach event , yet i'm thinking of creating a loop that continuously checks if the quantity has changed if so the program triggers an event that i'll use to update the text is that possible ?

I finally solved it , Thanks Lyqyd and Bomb Bloke

local brl = peripheral.wrap("bottom")
local mon = peripheral.wrap("top")
local infbrl = {}
local name = ""
local qty = 0
local div = 0
local mod = 0
local inf = true
repeat
infbrl = brl.getStoredItems()
name = infbrl.display_name
qty = infbrl.qty
mod = qty%64
if mod > 1 then
div = math.ceil(qty/64)-1
else
div = math.ceil(qty/64)
end
mon.clear()
mon.setCursorPos(1,1)
mon.setTextColor(colors.blue)
mon.write(name.." = "..qty.." ("..div.." x 64 + "..mod..")")
os.sleep(3)
until inf == false
