|

|
|
*
|
|||
|
|
* Purpose: Create two datasets (one for version 1 and one for version 2 of
|
|||
|
|
* the layout message), which should have dimensions too large to
|
|||
|
|
* represent in version 1 & 2 of the storage layout message.
|
|||
|
|
* This program is used to create the test file `tlayouto.h5' which
|
|||
|
|
* has truncated dimension information and can be used to verify that the
|
|||
|
|
* library has fixed up the storage size correctly.
|
|||
|
|
* To build the test file, this program MUST be compiled and linked
|
|||
|
|
* with version hdf5-1.6.2 or _earlier_ libraries and the generated test
|
|||
|
|
* file must be put into the 'test' directory in the 1.7+ (or 1.6+) branch
|
|||
|
|
* of the library.
