H5P

Detailed Description

Use the functions in this module to manage HDF5 property lists and property list classes. HDF5 property lists are the main vehicle to configure the behavior of HDF5 API functions.

Typically, property lists are created by instantiating one of the built-in or user-defined property list classes. After adding suitable properties, property lists are used when opening or creating HDF5 items, or when reading or writing data. Property lists can be modified by adding or changing properties. Property lists are deleted by closing the associated handles.
