Re: calling D2 routines from C routines on linux

[Charles Hixson]

I notice I've skipped the main reason.
What I'd like to do is build libraries in D that I can call from 
multiple languages.  C, Python, C++, Ada, Fortran, Lisp, whatever.  Just 
about every language has a C interface.  So if I can call the library 
from C, then I can call it from anywhere.  (Possibly except D.  Not sure 
about that, but I think the runtime functions might clash.)

See if this works for you:

import core.runtime;

void myMainFunc()
{
}

extern (C)
int initializeDee()
{
     int result;
     void exceptionHandler(Throwable e) { throw e; }

     try
     {
         Runtime.initialize(&exceptionHandler);
         result = myMainFunc();
         Runtime.terminate(&exceptionHandler);
     }
     catch (Throwable o)
     {
         result = 0;
     }
     return result;
}

This is similar to how it's done for Windows GUI applications, where
we have to manually run the initialize function in druntime (unless
it's hidden by some GUI framework).
