If some unprotected shared data exists for the * dataset (eg, a count of the number of attributes in the * dataset), there is a small chance that consecutive reads occur * before a write to that shared variable. * * HDF5 APIs exercised in thread: * H5Acreate2, H5Awrite, H5Aclose. * * Created: Oct 5 1999 * Programmer: Chee Wai LEE * * Modification History * -------------------- * * 15 May 2000, Chee Wai LEE * Incorporated into library tests. * * 19 May 2000, Bill Wendling * Changed so that it creates its own HDF5 file and removes it at cleanup * time. * ********************************************************************/
