Description:
HTML Wrap
classhdf-rm-section

H5P_GET_LAYOUT returns the layout of the raw data for a dataset. This function is only valid for dataset creation property lists.

Note that a compact storage layout may affect writing data to the dataset with parallel applications. See note in H5D_WRITE documentation for details.

Returns the layout type (a non-negative value) of a dataset creation property list if successful. Valid return values are:

H5D_COMPACT:  Raw data is stored in the object header in the file.

H5D_CONTIGUOUS: Raw data is stored separately from the object header in one contiguous chunk in the file.

H5D_CHUNKED:  Raw data is stored separately from the object header in chunks in separate locations in the file.

H5D_VIRTUAL:  Raw data is drawn from multiple datasets in different files.

Otherwise, returns a negative value indicating failure.
