Shown below is a simple program that encodes sample data using a customised, periodic memory layout specified for each of the columns independently, before outputting an ODB-2 file.
.. tabs::
.. group-tab:: C
.. literalinclude:: ../../../tests/c_api/odc_encode_custom.c
:language: c
:class: copybutton
To use this sample program, invoke it from the command line with a path to an ODB-2 output file:
.. code-block:: none
./odc-c-encode-custom example.odb
Written 20 rows to example.odb
.. code-block:: none
odc ls example.odb
