H5D_READ_CHUNK reads a raw data chunk as specified by its logical
offset in a chunked dataset
dset_id from the dataset in the file into the application memory buffer
buf. The data in
buf is read directly from the file bypassing the library’s internal data transfer pipeline, including filters.
dxpl_id is a data transfer property list identifier.
offset is an array specifying the logical position of the first element of the chunk in the dataset’s dataspace. The length of the offset array must equal the number of dimensions, or rank, of the dataspace. The values in
offset must not exceed the dimension limits and must specify a point that falls on a dataset chunk boundary.
filters indicates which filters are used with the chunk when written. A zero value indicates that all enabled filters are applied on the chunk. A filter is skipped if the bit corresponding to the filter’s position in the pipeline (
0 ≤ position < 32) is turned on.
buf is the memory buffer containing the chunk read from the dataset in the file.
