The void does datatype does not have a size, so that will not work. Yes, void ** can exist.
What are you trying to accomplish?

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it:
(1) one is to pass a pointer-to-pointer parameter, like:

{
*pmem=(char *)malloc(size);
if(*pmem==NULL)... (11 Replies)

I have a function to which I will pass a struct ID and it will return me a string.
I will pass a pointer to store the name string and that pointer will be allocated memory by the function called.

mpi_type_c2f
MPI_Type_c2f(3) LAM/MPI MPI_Type_c2f(3)
NAME
MPI_Type_c2f - Convert a datatype handle from its C representation to its Fortran representation
SYNOPSIS
#include <mpi.h>
MPI_Fint
MPI_Type_c2f(MPI_Datatype datatype)
INPUT PARAMETER
datatype
- C datatype handle
RETURN VALUE
f_handle
- Fortran datatype handle
NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list. ierr
is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked
with the call statement.
All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.
ERRORS
This function does not return the normal MPI_SUCCESS integer value upon success. Instead, it returns a handle to the converted object. If
an error occurs, the appropriate NULL handle will be returned.

For more information, please see the official MPI Forum web site, which contains the text of both the MPI-1 and MPI-2 standards. These
documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).
