What is the purpose of base parameter in JSON API message function

In the Message function the parameter "word base" (second parameter) is not documented on http://sdk.innovaphone.com/common/interface/json_api.htm#Message . What is it's purpose? It seems to be 0 all the time...

Re: What is the purpose of base parameter in JSON API message function

Hi Wim,

base is a reference to a certain object or array inside the json_io library.

It's explained inside the json_io doc:

http://sdk.innovaphone.com/common/ilib/json.htm

It's indeed zero if you reference the root object.

Greetings,

Daniel

Re: What is the purpose of base parameter in JSON API message function

I understand and read the documentation on json_io. But, why is it in that function provided as input parameter, and, is this always 0, or can this also have other values when that function is called? That's the part that is not documented and if you provide it as a parameter I assume it can have different values as well... or do I worry too much

(try to look at it from a person who doesn't know the internals like you do, and then you question every function)

Hi Wim,

I added the parameter to the documentation. Available in the next SR.

word base

The ID of the base element of the message inside the msg structure. Pass it to the get functions of json_io to read the attributes of the message. Example:

const char * text = msg.get_string(base, "text");
