60 The function <STRONG>new_item</STRONG> allocates a new item and initializes
61 it from the <STRONG>name</STRONG> and <STRONG>description</STRONG> pointers. Please notice
62 that the item stores only the pointers to the name and
63 description. Those pointers must be valid during the life-
64 time of the item. So you should be very careful with names
65 or descriptions allocated on the stack of some routines.
66 The function <STRONG>free_item</STRONG> de-allocates an item. Please notice
67 that it is the responsibility of the application to
68 release the memory for the name or the description of the
