Calling Pattern

Call

local k = sl.linklist()
-- later
local r = k.removelink(a)

Arguments

a is a number

Results

r is a number

Example Usage

local k = sl.linklist()
local j = k.inserta(0,'one')
j = k.inserta(j,'two')
j = k.inserta(j,'three')
k.remove(j)
print(k.value(k.tail()))
--> two

Description

Calling removelink detaches and recycles a valid link with pseudo-index a. The value associated with the link is lost. If successful, a is echoed in the return value. If the list is empty, or if a is otherwise an invalid pseudo-index, removelink returns 0.
