Frame Headers
=============
Shown below is a simple program that outputs information extracted from the header of each frame in an ODB-2 data stream, without actually decoding the data.
.. tabs::
.. group-tab:: C
.. literalinclude:: ../../../tests/c_api/odc_header.c
:language: c
:class: copybutton
To use this sample program, invoke it from the command line with a path to one or more ODB-2 files:
.. code-block:: none
./odc-c-header example.odb span.odb
File: example.odb
Frame: 1, Row count: 3, Column count: 5
Property: encoder => odc version 1.3.0
Column: 1, Name: int_column, Type: integer, Size: 8
Column: 2, Name: real_column, Type: real, Size: 8
Column: 3, Name: str8_column, Type: string, Size: 8
Column: 4, Name: str16_column, Type: string, Size: 16
