title: Is auto-chunking enabled by default when GZIP compression is used in the HDF5 C++ api?
body: <p>I am writing an HDF5 file using the C++ HDF api and performing a few comparisons against the H5py Python library. </p>
  
  <p>In the H5py Python library <a href="https://www.safaribooksonline.com/library/view/python-and-hdf5/9781491944981/ch04.html" rel="nofollow">autochunking</a> is applied by default when a compression algorithm such as GZIP or LZF is used.</p>
  
  <p>Does the same condition apply to the HDF5 C++ api?  If so, how can I prove that chunks were automatically created when a compression algorithm, such as GZIP,  was applied to the data sets.</p>
