+/// Get the list of all nodes by time they were last reachable.
+/** This function returns a list with handles for all the nodes whose last known reachability time overlaps with the given time range.
+ * If the range includes 0, it will count nodes that were never online.
+ * If start is bigger than end, the result will be inverted.
+ *
+ * \memberof meshlink_handle
+ * @param mesh A handle which represents an instance of MeshLink.
+ * @param start Start time.
+ * @param end End time.
+ * @param nodes A pointer to a previously allocated array of pointers to struct meshlink_node, or NULL in which case MeshLink will allocate a new array.
+ * The application can supply an array it allocated itself with malloc, or the return value from the previous call to this function (which is the preferred way).
+ * The application is allowed to call free() on the array whenever it wishes.
+ * The pointers in the array are valid until meshlink_close() is called.
+ * @param nmemb A pointer to a variable holding the number of nodes that were reachable within the period given by @a start and @a end.
+ * In case the @a nodes argument is not NULL, MeshLink might call realloc() on the array to change its size.
+ * The contents of this variable will be changed to reflect the new size of the array.
+ *
+ * @return A pointer to an array containing pointers to all known nodes that were reachable within the period given by @a start and @a end.
+ * If the @a nodes argument was not NULL, then the return value can either be the same value or a different value.
+ * If it is a new value, the old value of @a nodes should not be used anymore.
+ * If the new value is NULL, then the old array will have been freed by MeshLink.
