This change would break users so we can't do it this way. It would also make users responsible for closing the response descriptors. In what situations do you need to know the content of non-error responses?

[tarekbadrsh]

• I was need the whole response result (postid, etc ...).
• you are right in the issue about user close the connection we can solve by return (struct type with define property or byte array )
• we can let the currant interface as it's and create another return response

please feel free to ask about update and i will.
