Client Desires to Determine the Variable-Sized Chunk Information for a Dataset:
Pre-conditions:
- File is opened by client.
- Dataset is opened by client.
Scenario:
- Client retrieves dataset creation property list (DCPL) for dataset.
- Client queries the DCPL whether the chunks are identical or variable
sized.
- Client queries the DCPL whether the chunks are overlapping or
non-overlapping.
- If the chunks of variable-sized, the client may perform further
queries:
- Client queries the number of chunks defined.
- Client iterates over the number of chunks and queries the
region defined for each chunk into a dataspace selection.
Notes:
- The description of each chunk should be placed in a different dataspace
selection, if they will be used for separate I/O operations in the
future.
