Golang sqlite3_result_null Examples

Example #1

File: callback.go Project: mattn/go-sqlite3

func callbackRetBlob(ctx *C.sqlite3_context, v reflect.Value) error {
	if v.Type().Kind() != reflect.Slice || v.Type().Elem().Kind() != reflect.Uint8 {
		return fmt.Errorf("cannot convert %s to BLOB", v.Type())
	}
	i := v.Interface()
	if i == nil || len(i.([]byte)) == 0 {
		C.sqlite3_result_null(ctx)
	} else {
		bs := i.([]byte)
		C._sqlite3_result_blob(ctx, unsafe.Pointer(&bs[0]), C.int(len(bs)))
	}
	return nil
}

	C.sqlite3_result_null(c.sc)
}
