+ * The iteration begins with the idx object in the group and the next element

+ * iterator starts at zero.
+ *
+ * Parameters:
+ *
+ * hid_t DID; IN: the dataset
+ * unsigned int dim; IN: the dimension of dset
+ * int *idx; IN/OUT: input the index to start iterating, output the next index
+ * to visit. If NULL, start at the first position.

+ * void *visitor_data; IN: arbitrary data to pass to the visitor function.
