Hello everyone.
I've been using DLL's in D for a long time but just recently i'm having a
problem. Lets see if someone can help me a bit.

I have several lines of code but i'll use an example from the DMD site wich is
almost the same come.

Read the DMD site about DLL's here: http://www.digitalmars.com/d/1.0/dll.html

Check for the section "D code calling D code in DLLs".

If you extern(C) all exports in mydll.d and change all symbols in test.d to
their C respectives, when running you'll get access violation.

Any ideas?

I attached a rar file with the sources just to see what i'm talking about. The
example is from the DMD site. Included is the extern D (ok) and the extern C
(fails). To compile open "compile.bat" and to run the programs use "run.bat".

Try this:
alias extern (C) void function(void*) MyDLL_Initialize_fp;
alias extern (C) void function() MyDLL_Terminate_fp;
alias extern (C) MyClass function() getMyClass_fp;
