Release information for the 10/10/97 prototype release:
|
|
|
|
This release is intended primarily as a proof of concept and as a method
|
|
of familiarizing users with the intended functionality. 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. [This list is
|
|
short, mainly as a method of providing feedback before significant direction
|
|
changes must be made]
