How to parse Datum

From
"Zhe He"
Date:
I met a problem with parsing Datum,
is there any good way to parse this
kind of value? Because I want to get
the value in an attribute of a table.
In TupleTableSlot, there is a tts_values
which is Datum type. Does anyone know how
to parse it?

Best Regards,

There are several macros like DatumGetInt and so on. See postgres.h for details.
