 *              removed in the future.  Applications should switch to the
 *              newer APIs.

NAME
   H5F_init_deprec_interface -- Initialize interface-specific information
USAGE
    herr_t H5F_init_deprec_interface()
RETURNS
    Non-negative on success/Negative on failure
DESCRIPTION
    Initializes any interface-specific data or routines.  (Just calls
    H5F_init() currently).

 * Function:    H5Fget_info1
 *
 * Purpose:     Gets general information about the file, including:
 *		1. Get storage size for superblock extension if there is one.
 *              2. Get the amount of btree and heap storage for entries
 *                 in the SOHM table if there is one.
 *		3. The amount of free space tracked in the file.
 *
 * Return:      Success:        non-negative on success
 *              Failure:        Negative
