Available since: Gideros 2011.6
Class: (global)
Description
Returns three values: an iterator function, the table t, and nil, so that the construction:
for i,v in pairs(t) do body end
will iterate over any key pairs (indexed or associative) even with nil values.
(function), (table), (nil) = pairs(t)
Parameters
t: (table) table to iterate
Return values
Returns (function) iterator function
Returns (table) provided table
Returns (nil) nil value
