Call to SPGetFieldValue returns 0 on invalid FieldName.

Making a call to SPGetFieldValue passing "" or even "nonsense" for chFieldName parameter returns 0 as the result. According to the documentation it should return a result < 0. Has this changed and not been updated in the documentation? Is there a way to know if a field name is invalid compared to a valid one that has an empty string as the value?

The documentation is wrong for that function. SPGetFieldValue returns the length of the data in the field. If you pass in a bad field name it will return zero. I'll put a bug in to get that fixed so that the API returns < 0 value for a bad field name.
SPSetFieldValue (on the other hand) will return an error if you pass in a bad field name.You will get a -104 error code in that scenario.
