 * Function:	main
 *
 * Purpose:	To create HDF5 files with non-zero status_flags in the superblock
 *		via flushing and exiting without closing the library.
 *
 *		Due to file locking, status_flag in the superblock will be 
 *		nonzero after H5Fcreate.  The library will clear status_flags
 *		on file closing.  This program, after "H5Fcreate" the files,
 *		exits without going through library closing. Thus, status_flags
 *		for these files are not cleared and users cannot open them.
 *
 *		These files are used by "h5clear" to see if the tool clears
 *		status_flags properly so users can open the files afterwards.

 * Return:	Success:	0
