UDF, Is it really possible to write UDF's DLL's with delphi (and make 'em work too?)

Yes, it is possible.

Are you declaring the UDF in your database?

Download, as an example, the FreeUDFLib, I think it was created with Delphi,
you can find it here: http://www.mers.com/download.html

Whatever I tried ,I always get the message 'Function is undefined ,could not
locate ModuleName or
entryPoint', With WISQL ,all I get is SQL error -104 (where do I get more
detailed error message ?)
, does anyone know if and how it's possible to write a working UDF with
delphi ?

Yes it is possible and it seems to be easy.
I've had the same question yesterday and I've downloaded FreeUDFLib
and read this http://www.ibphoenix.com/ibp_howto5.html
and now I've already my own DLL for special issues of my projects.
To write String-functions I'm using a copy of udf_glob.pas
(MakeResultString)

Yes it is possible and I have done it. I will look around and see if I can
find my UDF code.
