Returns the tier and column of a talent's prerequisite, and if the talent is learnable. 

tier, column, isLearnable = GetTalentPrereqs( tabIndex , talentIndex[, inspect] );

Parameters[edit]

Arguments

(tabIndex, talentIndex)
tabIndex
Integer - Specifies which tab the talent is in.
talentIndex
Integer - Specifies which talent to check
Note: The talentIndex is counted as if it where a tree, meaning that the left most talent in the top most row is number 1 followed by the one immediate to the right is number 2, if there are no more talents to the right then it continues from the left most talent on the next row.
inspect
Boolean - If true returns the information for the inspected unit instead of the player. New with 2.3.

Returns

tier, column, isLearnable
tier
Integer - The tier that the prerequisite talent sits on
column
Integer - The Column that the prerequisite talent sits on
isLearnable
Integer - Returns 1 if you have the necessary prereqisites already, nil otherwise.


Example[edit]

For a Warrior, checks the prerequisites for the talent "Flurry": 

local tier, column, learnable = GetTalentPrereqs(2,16)

Result 

tier = 4
column = 3
learnable = 1 if you have 5/5 in Enrage, nil otherwise

Details[edit]

If you select a talent with no prerequisites, the whole function returns nil

The original code by Blizzard shows that possibly several prerequisites could exists, in which case other triplets of row, column, learnable values would be returned. Code to handle this would look like this : 

local handle_prereqs = function (...)
  for i = 1, select("#", ...), 3 do
    local row, column, learnable = select(i, ...)
    <do something here>
  end
end
handle_prereqs(GetTalentPrereqs(tab, index))
