Hi all,

I'm programming an interface board, connected with the PC using the parallell (printer, LPT1) connection. I have to choose between using a DLL or toggle the ports directly (I know which port adresses are used). Which way is best (provided that I want to keep my application platform independent)?
How can I include a DLL in a C++ program?
OR
How do I toggle ports in C++? Is it OS dependent? Do you need certain privileges to do this under Linux?

Don't worry what people think about you. They're too busy wondering what you think about them.

Bertv100 - seems like I have seen that name somewhere else lately ;-)
Not exactly a C++ solution, but maybe something worth looking at:

If it was only the ports, I would certainly use Pascal (on an old DOS PC, that is, because I can't get access to ports on a winxp running machine). However, I also need multithreading and a GUI (I was thinking of wxWindows).

FreePascal has bindings for GTK on Windows and Linux,
and also has bindings for the pthreads library.

But if you want a C++ library, maybe you can find something here:
