int json_list_object_array_value_add_null

(

list_object *

list_to_add

)

Add a new null value to a JSON Array, defined by the list_object provided.

This function will add a new value element to the provided list_object at the last position of that list.

This function only supports adding value type null.

If there are already elements in this list_object, then they are used to confirm that the list_object requested, is actually a JSON Array. If this is the first element to be added, then as no check can be made, it is assumed the caller is providing a value to a valid JSON list type. If the list type is incorrect, an error will be thrown up when the second element is added.

Parameters

[in]

list_to_add

the list_object of the JSON data hierarchy to add the new value to.

Return values

LIST_OK	success, new element added to the list
LIST_ERR	on error
