How to process OUTPUT parameters from stored procedures?

I understand that to allocate space for output parameters of stored
procedures you call the Sybase.OUTPUT() function with an appropriate
type. I can't figure out what to do with the resulting output
parameter dictionary's value. If my input parameters contain such and
OUTPUT() function result:

    params = {
        ...
        '@result': Sybase.OUTPUT(1),
        ...
    }

the return value is a dictionary whose "@result" key is an instance of
DataBufType. None of the attributes of that instance seem to suggest
how to extract the actual output value in terms of a usable Python
data type. How do I get that value?

Thx,
