XPLMDataTypeID
This is an enumeration that defines the type of the data behind a data reference. This allows you to sanity check that the data type matches what you expect. But for the most part, you will know the type of data you are expecting from the online documentation.
Data types each take a bit field; it is legal to have a single dataref be more than one type of data. Whe this happens, you can pick any matching get/set API.
