* Purpose: Create a dataset with a null dataspace and an attribute
* with a null dataspace.
* This program is used to create the test file `tnullspace.h5' which
* has dataspaces stored in the newer (version 2) style in the object headers.
* To build the test file, this program MUST be compiled and linked with
* the hdf5-1.7+ series of libraries and the generated test file must be
* put into the 'test' directory in the 1.6.x branch of the library.
