char ***argc problems.

[Andrew]

I'm attempting to create a wrapper for MPI, however, MPI_Init
wants to read the arguments for main():

MPI_Init(int *argv, char ***argc);

How do I get this last level of pointer reference?

So far, I have:

void main (string[] args)
{
     auto argarr = new char*[args.length];
     foreach(i, a; args)
         argarr[i] = (a.dup ~ '\0').ptr;

     int argc = to!(int)(argarr.length);
     MPI_Init(&argc, argarr.ptr);
}

Any ideas?
