== Calling Pattern ==
Call
local k = sl.linklist()
-- later
local n = k.getposition(a[,b])

Arguments
a is a number
b optional, is a boolean

Results
n is a number

== Example Usage ==

local k = sl.linklist()
local j = k.insertb(0,'one')
local j0 = j
j = k.insertb(j,'two')
j = k.insertb(j,'three')
print(k.getpos(j0))
print(k.getpos(j))

== Description ==

Calling getposition returns the absolute position of a link psuedo-index relative to the head of the list. If b is specified and has a value of false then getposition returns the position relative to the tail of the list. Positions run from 1 to the length of the linked list.

+Calling getposition returns the absolute position of a link psuedo-index relative to the head of the list. If b is specified and has a value of false then getposition returns the position relative to the tail of the list. Positions run from 1 to the length of the linked list.  If the parameter supplied is an invalid pseudo-index, then getposition returns 0. ** There is an error in version 0.06 that will be corrected in later versions.  If b is false, getposition will return the wrong values if the pseudo-index is either the head or tail of the list.**
