thanks for your info, I will try to extend these tests to see the results and post it here if relevant about speed I doubt that it will be affected arab http://nomade.sf.net --- Em ter, 26/4/11, LRN <lr...@gm...> escreveu: De: LRN <lr...@gm...> Assunto: Re: [Mingw-users] dll created in a different way Para: min...@li...

And the actual question about the implications. Sorry. Lots of things on my mind right now. (You DID try -mconsole and/or -mwindows though? Does it make a difference? Would be a good thing to know whether these options affect DLLs) As for implications...i'm not aware of any. OTOH you can export functions from an executable, that is - use an executable file as a library. So it MIGHT be technically possible (unless someone can give me a prooflink to PE specs that shows otherwise) to execute a DLL (instead of importing functions from it)...And that wouldn't work without main() or WinMain() anyway...so, i guess subsystem type still doesn't matter. And since we're talking about it...have you ever tried to exec() a DLL? Or use CreateProcess() on it? I didn't (which is why i'm asking). ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
