##########################################

*Size of the validation buffer for the incoming data*

Type: ``int``

Help
====

.. code-block:: none

    LwM2M will use the validation buffer during the write operation, to
    decode the resource value before validating it (applies for resources
    for which validation callback has been registered). Set this value to
    the maximum expected size of the resources that need to be validated
    (and thus have validation callback registered).
    Setting the validation buffer size to 0 disables validation support.
