Name: H5Pset_layout
Signature:
herr_t H5Pset_layout( hid_t plist, H5D_layout_t layout )

Purpose:
Sets the type of storage used to store the raw data for a dataset.

Description:
H5Pset_layout sets the type of storage used to store the raw data for a dataset. This function is only valid for dataset creation property lists.

Valid values for layout are:

H5D_COMPACT
Store raw data in the dataset object header in file. This should only be used for datasets with small amounts of raw data. The raw data size limit is 64K (65520 bytes). Attempting to create a dataset with raw data larger than this limit will cause the H5Dcreate call to fail.
H5D_CONTIGUOUS
Store raw data separately from the object header in one large chunk in the file.
H5D_CHUNKED
Store raw data separately from the object header as chunks of data in separate locations in the file.
H5D_VIRTUAL
Draw raw data from multiple datasets in different files.

Note that a compact storage layout may affect writing data to the dataset with parallel applications. See note in H5Dwrite documentation for details.

Parameters:
hid_t plist IN: Identifier of property list to query.
H5D_layout_t layout     IN: Type of storage layout for raw data.

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