Multiple choice.

If the Application Programming Interface (API) Instance's error code is set to 0, then one of the assumptions is

  • An attempt was made to retrieve a value for a data element after communication had been terminated.
  • The data model element passed as parameter in GetValue or parameter_1 in SetValue is recognized as a valid element but is not supported.
  • An attempt was made to retrieve a value for a data element before communication had been initialized.
  • Any values that were set (using the SetValue() method call) since Initialize("") or the last Commit("") method call, have been successfully forwarded to the persistent data store.

Correct. If the API Instance's error code is set to 0, then one of the assumptions is that any values that were set (using the SetValue() method call) since Initialize("") or the last Commit("") method call, have been successfully forwarded to the persistent data store.
