Has anyone successfully made a working UDF that uses one or more of the calls to firebird (e.g. ib_util_malloc or isc_encode_date ...)?

I cannot get the syntax for the two firebird .lib (or .dll) files on the compile line.

GCC is much smaller and quicker to install than Microsoft's compiler, cheaper than Borland's, and does not require special prefixes for the function declarations (__export __cdecl).

If so, please post an example compile line.
