DESCRIPTION
       The function new_item allocates a new item and initializes it from the name and description pointers.
       Please notice that the item stores only the pointers to the name and description. Those pointers must
       be  valid  during  the lifetime of the item. So you should be very careful with names or descriptions
       allocated on the stack of some routines.
       The function free_item de-allocates an item. Please notice that  it  is  the  responsibility  of  the
       application to release the memory for the name or the description of the item.
