nthData
Gets the data of the element at the given position.
This iterates over the list until it reaches the @n-th position. If you intend to iterate over every element, it is better to use a for-loop as described in the #GList introduction.
Return
the element's data, or null if the position is off the end of the #GList
Parameters
list
a #GList, this must point to the top of the list
n
the position of the element
