+ - H5Dget_chunk_storage_size
+
+ The storage size of a chunk in the file is needed to determine the size
+ of the buffer to be allocated for reading a chunk directly from a file.
+
+ New API function gets the size in bytes currently allocated within a
+ file for a raw data chunk in a dataset. This function was added to get
+ the chunk size in support of the implementation of H5DOread_chunks, but
+ may also be useful for other purposes.

- H5DOread_chunk
+
+ Users wanted to read compressed data directly from a file without any
+ processing by the HDF5 data transfer pipeline, just as they were able
+ to write it directly to a file with H5DOwrite_chunk.
- New API function, H5DOread_chunk, corresponding to existing function
- H5DOwrite_chunk. H5DOread_chunk reads a raw data chunk directly from a
- chunked dataset in the file into the application buffer, bypassing the
- library’s internal data transfer pipeline, including filters.
