* Function: H5Fset_latest_format

* Purpose: Enable switching between latest or non-latest format while

|

* 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.
