Linux DLL

[Mineko]

So, I was doing some stuff with shared libraries and need some 
confirmation on what's going on with 
http://dlang.org/dll-linux.html

Is that page recent, or really old?

It's using printf and stuff so uhh.. Seems old.

Could anyone here perhaps give me a more recent explanation of 
how to do the bottom example, if it's not already? 
(http://dlang.org/dll-linux.html#dso10)

Using the standard phobos library, of course, for instance, I 
would have issues with fprintf and the stuff going on with 
stderror and error/dlerror.
