hid_t dset_id    

IN: Dataset identifier

hsize_t *offset

IN: Pointer to a one-dimensional array with a size equal to the dataset’s rank. Each element is the logical position of the chunk’s first element in a dimension.

unsigned *filter_mask

OUT: Filter mask indicating which filters were 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. If the chunk does not exist the value at the pointer location is not modified.

haddr_t *addr

OUT: Chunk address in the file; if chunk does not exist the address is set to HADDR_UNDEF

hsize_t *size

OUT: Chunk size in bytes; if chunk doesn’t exist the size is set to 0


H5D_GET_CHUNK_INFO_BY_COORD retrieves the filter mask filter_mask, size size and address addr for a chunk in the dataset specified by the dataset identifier dset_id, using the coordinates specified by offset. If the queried chunk does not exist in the file, the size will be set to 0 and the address to HADDR_UNDEF. The value pointed to by filter_mask will not be modified.


Returns a non-negative value if successful. Otherwise returns a negative value.
