tag.i4.v = put(list.s.r, item.g.r, size.i4.v)
This method appends an element to the tail of the List.
The List class actually allocates new space in which to store
the data item, and makes its own copy of it, so that the original
does not need to be kept after it has been "put" into the List.
list a pointer to the list (structure of type List)
item a pointer (of any type) to the item to be stored
size the size of the item (in bytes)
This function returns:
an integer tag which can be used for subsequent pseudo-random
retrieval of the item stored in the List.
Use of this class requires the following header files:
create_List() the constructor for instances of the List class
tag = (*list->put)(list,(void *) &item,sizeof(item));
