writeChunk

void writeChunk(hid_t datasetId,  uint  filters,  const  hsize_t *  offset,
                 size_t dataSize,  const  void *  data,  hid_t dxpl =  H5P_DEFAULT)

Writes a raw data chunk directly to a chunked 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

`datasetId`	Dataset identifier (must be chunked)
`filters`	Filter mask indicating which filters were applied to the data
`offset`	Logical position of the chunk within the dataset
`dataSize`	Size of the chunk data in bytes
`data`	Buffer containing the chunk data to write
`dxpl`	Dataset transfer property list (default: H5P_DEFAULT)

Throws

HDF5Exception if the write operation fails

Example:

// Write a pre-compressed chunk at position [0, 0]
hsize_t[2] offset = [0, 0];
ubyte[] compressedData = compress(rawData);
writeChunk(dataset.handle(), 0, offset.ptr, compressedData.length, compressedData.ptr);

void writeChunk(size_t N)(hid_t datasetId,  uint  filters,  const  hsize_t[N]  offset,
                           size_t dataSize,  const  void *  data,  hid_t dxpl =  H5P_DEFAULT)

Writes a raw data chunk directly to a chunked dataset (array overload).

Parameters

`datasetId`	Dataset identifier (must be chunked)
`filters`	Filter mask indicating which filters were applied to the data
`offset`	Logical position of the chunk within the dataset
`dataSize`	Size of the chunk data in bytes
`data`	Buffer containing the chunk data to write
`dxpl`	Dataset transfer property list (default: H5P_DEFAULT)

Throws

HDF5Exception if the write operation fails

void writeChunk(T)(hid_t datasetId,  uint  filters,  const  hsize_t *  offset,
                    const  T[]  data,  hid_t dxpl =  H5P_DEFAULT)

Writes a raw data chunk directly to a chunked dataset (slice overload).

This overload accepts a typed array slice and automatically calculates the data size.

Parameters

`datasetId`	Dataset identifier (must be chunked)
`filters`	Filter mask indicating which filters were applied to the data
`offset`	Logical position of the chunk within the dataset
`data`	Array slice containing the chunk data to write
`dxpl`	Dataset transfer property list (default: H5P_DEFAULT)

Throws

HDF5Exception if the write operation fails
