Karsten,

    Passing parameters by descriptor was a regular part of the
UDF interface until V4 when the SQLization committee decided
it was too complicated to explain.  You don't have to do anything
on the calling side - the engine understands passing modes and
will allocate the descriptor and interpret it on return.  At least
it did.  Digging that stuff out was on my list of chores - way
below the top, alas.  If I can be of any assistance, let me know.
