H5DOwrite_chunk

herr_t H5DOwrite_chunk(hid_t dset_id,  hid_t dxpl_id,  uint  filters,
                           const  hsize_t *  offset,  size_t data_size,  const  void *  buf)

Writes a raw data chunk directly to a dataset.

This function writes a chunk of raw data directly to storage, bypassing the filter pipeline. This is useful when the application handles compression externally and wants to write pre-compressed data.

Parameters

`dset_id`	Dataset identifier (must be chunked)
`dxpl_id`	Dataset transfer property list identifier
`filters`	Filter mask indicating which filters were applied to the data
`offset`	Logical position of the chunk within the dataset
`data_size`	Size of the chunk data in bytes
`buf`	Buffer containing the chunk data to write

Returns

Non-negative on success, negative on failure.

Note

This is a compatibility wrapper. For HDF5 1.10.3+, use H5Dwrite_chunk directly.
