I guess you made a typo in your select statement, since it calls round, not pround. It would appear that Firebird cannot load the dll/so or find the entry point to the function in the dll. Did you copy the dll/so to the UDF subdirectory of your Firebird diretory? You could also try adding the extension (.dll or .so) to the name of the library. If you are using Linux you should also check the permissions on the library and make sure that Firebird can load it. If this doesn't work, open the Firebird.conf file and check what the value for UdfAccess is. You may also have to change the calling convension of your function to cdecl, since that is what Firebird expects.
