Test zlib with subfiling.

minimal viable test

(1) It is important to create a new test function instead of modifying the behavior of an existing one.
(2) In your code, you have created a variable called "plist_id," but it is not being used, so compression is not performed. A thorough test should identify this issue.

@brtnfld , thanks for reviewing quickly!

What do you mean by plist_id is not being used. E.g., I thought the following uses plist_id:

VRFY((H5Pset_chunk(plist_id, 1, chunk_dims) >= 0), "H5Pset_chunk succeeded");

Please help me what I missed.

It should be for chunked/compressed dataset,

dset_id = H5Dcreate2(file_id, "DSET", SUBF_HDF5_TYPE, fspace_id, H5P_DEFAULT, plist_id, H5P_DEFAULT);
