dbplus_curr() will read the data for the previous tuple for the given relation, will make it the current tuple and will pass it back as an associative array in tuple.
The function will return zero (aka. DBPLUS_ERR_NOERR) on success or a db++ error code on failure. See dbplus_errcode() or the introduction to this chapter for more information on db++ error codes.
