Name: H5Dget_chunk_storage_size

Signature:

herr_tH5Dget_chunk_storage_size( hid_t dataset_id, const hsize_t *offset, hsize_t *chunk_nbytes )

Purpose:

Returns the amount of storage allocated within the file for a raw data chunk in a dataset.

Description:

H5Dget_chunk_storage_size returns the size in bytes allocated in the file for a raw data chunk as specified by its logical offset in the dataset dataset_id. The size is returned in chunk_nbytes. It is the size of the compressed data if the chunk is filtered and the size may be zero if no storage is allocated yet for the dataset.

Parameters:

hid_t dataset_id	IN: Identifier of the dataset to query.
const hsize_t * offset	IN: Logical offset in the dataset for the chunk to query.
hsize_t * chunk_nbytes	OUT: The size in bytes for the chunk.

Returns:

Returns a non-negative value if successful; otherwise returns a negative value.
