Hi everybody,
I'm trying to understand how it works when you wanna send (in MPI) a
message that is a sequence of derived datatypes.
Now, my structure looks like (in C):

	struct IntList{
		int item;
		struct IntList *next;
        };

I know it looks trivial, but I already don't know how to go on: 
when I build the Type Map I know that the MPI Datatype for int is
MPI_INT, but what about a pointer?
Any suggestion?
Thanks
Luca
