Hi folks,

I've only used D on Linux so far, so I'm not clear on the current
shared-library story on Windows. Consider an existing C++ application that
can be extended by writing plugins, which are usually written in C or C++,
and compiled as DLLs. Very generally speaking, is DMD capable of producing
DLLs that could be used by such an application?

If so, should I expect runtime-related issues if I create multiple plugins
with DMD, and load them all into the app? (I recall some discussion about
runtime problems with multiple shared libs, but perhaps that was in the
context of a D program loading D shared-libs.)

Thanks,
Graham

Yep. Just be sure to use dll_helper as described in  
http://www.digitalmars.com/d/2.0/dll.html to intialize the runtime  
properly.

Never tried that.

Just remembering that I also created a COM dll with D to intercept  
DirectDraw calls in an old game.

Thanks, Trass3r et al! I'll give it a try in D, then.

Of course you can't create 64Bit dlls though ;)

D'oh! There's always something. :)

(I don't *think* this is a problem in my case, though.)
