• Versioned Functions and Struct with Associated Macros
• Property List Encoding and Decoding Functions
• External File Prefix Functions

Two functions in the HDF5 C interface, and a struct associated with one of those functions, have been versioned in this release. At the same time, interface compatibility macros were created for programmatic management of these functions. See API Compatibility Macros in HDF5 for a detailed discussion of versioned functions and structs and the related macros.

These functions, struct, and macros are documented in the HDF5 Reference Manual:

Functions have been added in the HDF5 C interface to encode and decode property lists.

These functions are documented in the HDF5 Reference Manual:

• H5Pencode
• H5Pdecode

Datasets that store raw data in external files can be created in HDF5. Functions have been added in the HDF5 C interface to enable such external files to be located via a relative path from the directory where the HDF5 file containing such a dataset is located:

These functions are documented in the HDF5 Reference Manual:

• H5Pset_efile_prefix
• H5Pget_efile_prefix
