 RETURNS

 DESCRIPTION
        This is the primary function for creating HDF5 files . The flags
    parameter determines whether an existing file will be overwritten or not.
    All newly created files are opened for both reading and writing.  All flags
    may be combined with the "||" (logical OR operator) to change the behavior
    of the file open call.
        The flags currently defined:
            H5ACC_OVERWRITE - Truncate file, if it already exists. The file will
                be truncated, erasing all data previously stored in the file.
        The more complex behaviors of a file's creation and access are
    controlled through the file-creation and file-access templates.  The value
    of 0 for a template value indicates that the library should use the default
    values for the appropriate template.  (Documented in the template module).
    [Access templates are currently unused in this routine, although they will
    be implemented in the future]
