I have a UDF that needs to takes a couple of CSTRING(255) arguments and returns
CSTRING(8000), but it needs to be able to handle accented characters like in
French..
The UDF is written in C and compiled in MS Visual Studio, using the normal
"char" character type. I tried changing that to
Stackoverflow.com ;-)
but do you think that it's time to upgrade?

I suppose you do some wrong things like:
1. Wrong calling convention – should by „cdecl” not „stdcall”
2. You allocate strings locally and return it to the engine but you should
allocate it by „ib_util_malloc”.
3. Your declaration of udf is wrong.
4. You raise some exceptions inside your udf

Hi all,
I'm using Firebird 2.5.8 and wrote a UDF that "returns" a large (~60MB) BLOB
via an output parameter that's a pointer to a blobcallback by repeatedly
calling blob_put_segment. The instructions for doing so I took from:

Hi,
i have an UDF function that runs perfectly on Linux 64 bit systems. I wanted to
port it to Windows 32 bit, but i'm having problems there.
The UDF was written in C (not C++), compiled on Linux with gcc, everything
works fine.
I compiled the same C file on Windows with MinGW Developer Studio
I’m having a weird error, sometimes the system crashes due to an UDF being not
declared properly :
“invalid request BLR at offset 877 function F_GFORMATD is not defined module
name or entrypoint could not be found”
But I can verify it is declared properly.
