A list of the -limitations of the prototype is as follows: - o - Multiple datasets may be created/read/written in an HDF5 file, but - access must be as an entire dataset, i.e. no slab/slice/subset code is - implemented yet. The datasets must also be homogeneous, orthogonal - datasets, similar to the datasets which are able to be created in the - HDF4 "SD" interface. Reducing these restrictions will be a major - effort of further development on the library. - o - Datasets can be located in a hierarchy of groups in the file, however - user-level features for transitioning through the groups are not - implemented in this release. Each dataset must be accessed through - its full "pathname" in the file, ie. "/foo/bar/dataset1", - "/foo/bar/dataset2", "/foo/data" - - This release has been tested on UNIX platforms only; specifically: Linux, -FreedBSD, IRIX, Solaris & Dec UNIX. Machines which do not have IEEE floating- -point representation or non big- or little-endian memory representations aren't -supported in this release, most other machines should work correctly. - - A list of the API functions currently supported follows.
