Hi all,

I must say I've failed to follow the existing UDF argument mechanisms...

From what I understood, Firebird 1 supports the "By Descriptor" output
argument mechanism. But does it also support this:

DECLARE EXTERNAL FUNCTION DPOWER
DOUBLE PRECISION BY DESCRIPTOR,
DOUBLE PRECISION BY DESCRIPTOR,
DOUBLE PRECISION BY DESCRIPTOR
RETURNS PARAMETER 3
ENTRY_POINT 'power' MODULE_NAME 'fbudf';

Or is this Fb 1.5?

If input parameters support BY DESCRIPTOR, what other
mechanisms do they support? By Value/Ref, Free It? Etc?

I can't see the forest from the trees here... Can someone help
me with this by spelling it out for me? (and no, I can't find
it in the release notes that I have :-/ ... )

With regards,
