===================================================
Example NeXus C programs using native HDF5 commands
===================================================

C-language code examples are provided for
writing and reading NeXus-compliant files
using the native HDF5 interfaces.  These examples are derived from the simple
NAPI examples for :ref:`writing <fig.ex-c-write>`
and :ref:`reading <fig.ex-c-read>` given in the
:ref:`Introduction <Introduction>` chapter.
Compare these code examples with :ref:`NAPI-Examples`.
