Get the key of the record where the cursor is.
|sp ||the pointer to a variable to which the size of the region of the return value is assigned. If it is 0, it is not used. |
- the pointer to the region of the key of the corresponding record.
|Villa_error ||if an error occurs or no record corresponds to the cursor. |
