! This example shows how to create and write a dataset attribute.
|
|
! It opens the existing file 'dset.h5', obtains the identifier of
|
|
! the dataset "/dset", defines attribute's dataspace,
|
|
! creates dataset attribute, writes the attribute, and then closes
|
|
! the attribute's dataspace, attribute, dataset, and file.
