How to write UDF in C++

Hi all,

could anybody give me an example of code in C++ of function declared like following.

DECLARE EXTERNAL FUNCTION Translate
CSTRING(100), CSTRING(100), CSTRING(100)
RETURNS CSTRING(100) FREE_IT
ENTRY_POINT 'Translate' MODULE_NAME 'Utils';

How does the declaration look like in C++.

I have a problem that if I call the function I get an error.

fmSQLEditor.Query:
Invalid token.
invalid request BLR at offset 63.
function TRANSLATE is not defined.
module name or entrypoint could not be found.

Thanks.

any error when change
from 'Translate' to 'TRANSLATE'?

there is one udf library written in c++ on sf.net
