/*-------------------------------------------------------------------------
* 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
* Failure: 1
*
* Programmer: Vailin Choi; July 2013
