+ * 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_flags 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.
+ *		The library will check consistency of status_flags when opening
+ *		a file with superblock >= v3 and will return error accordingly.
+ *		The library will not check status_flags when opening a file 
+ *		with < v3 superblock.
+ *
+ *		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
+ *		Failure:	1
+ *
+ * Programmer:	Vailin Choi; July 2013
