which attribute was UPDATEd in a trigger?

Hello,

I have this C trigger that sets a "modified" timestamp column to the
present date on each UPDATE to a row. This is fine unless I want to play
with the "modified" column itself, as the trigger dutifully resets it to
now() on any UPDATE. Is there a way inside the trigger to detect on
which column the UPDATE was called?

Thanks in advance,
