/********************************************************************
*
* Testing thread safety. Deliberate per-thread errors to test error stack
* -----------------------------------------------------------------------
*
* Create 16 multiple threads to create datasets with the same name. The
* library should respond with 15 equivalent error stack printouts (one for
* each bad thread). The final hdf5 file should be a valid file with one
* entry.
*
* Temporary files generated:
*
* ttsafe_error.h5
*
* HDF5 APIs exercised in thread:
*
* H5Screate_simple, H5Tcopy, H5Tset_order, H5Dcreate2, H5Dclose,
* H5Tclose, H5Sclose.
*
* Created: Apr 28 2000
* Programmer: Chee Wai LEE
*
* Modification History
* --------------------
*
* 19 May 2000, Bill Wendling
* Modified so that it creates a unique HDF5 file and removes it on
* cleanup.
