+ * Function: H5Fset_latest_format
+ *
+ * Purpose: Enable switching between latest or non-latest format while
+ * a file is open.
+ * This is deprecated starting release 1.10.2 and is modified
+ * to call the private H5F_set_libver_bounds() to set the
+ * bounds.
+ *
+ * Before release 1.10.2, the library supports only two
+ * combinations of low/high bounds:
+ * (earliest, latest)
+ * (latest, latest)
+ * Thus, this public routine does the job in switching
+ * between the two combinations listed above.
+ *
+ * Starting release 1.10.2, we add v18 to the enumerated
+ * define H5F_libver_t and the library supports five combinations
+ * as below:
+ * (earliest, v18)
+ * (earliest, v10)
+ * (v18, v18)
+ * (v18, v10)
+ * (v10, v10)
+ * So we introduce the new public routine H5Fset_libver_bounds()
+ * in place of H5Fset_latest_format().
+ * See also RFC: Setting Bounds for Object Creation in HDF5 1.10.0.
+ *
+ * Return: Non-negative on success/Negative on failure
+ *
+ * Programmer: Vailin Choi; December 2017
