H5D_WRITE_CHUNK writes a raw data chunk as specified by its logical
offset in a chunked dataset
dset_id from the application memory buffer
buf to the dataset in the file. Typically, the data in
buf is preprocessed in memory by a custom transformation, such as compression. The chunk will bypass the library’s internal data transfer pipeline, including filters, and will be written directly to the file.
dxpl_id is a data transfer property list identifier.
filters is a mask providing a record of which filters are used with the chunk. The default value of the mask is zero (
0), indicating that all enabled filters are applied. A filter is skipped if the bit corresponding to the filter’s position in the pipeline (
0 ≤ position < 32) is turned on. This mask is saved with the chunk in the file.
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.
data_size is the size in bytes of the chunk, representing the number of bytes to be read from the buffer
buf. If the data chunk has been precompressed,
data_size should be the size of the compressed data.
buf is the memory buffer containing data to be written to the chunk in the file.
