+Returns a @code{glibtop_map_entry *} list (which needs to be freed with

+@item number
+Number of entries in the returned list.

+Total size of the returned list (this equals @code{number * size}).
+
+@item size
+Size of a single entry in the returned list
+(this equals @code{sizeof (glibtop_map_entry)}).
