MPI_Get_address - Gets the address of a location in memory


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Get_address( location, address)
            void     *location;
            MPI_Aint *address;

       C++:

            #include <mpi.h>

            Aint Get_address(
            void*             location)

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            <type> LOCATION(*)
            INTEGER ierror
            INTEGER(KIND=MPI_ADDRESS_KIND) address

            CALL MPI_GET_ADDRESS(location, address, ierror)


DESCRIPTION

       The MPI_Get_address routine gets the address of a location
       in memory.  This routine is provided for both Fortran and
       C programmers.  On many systems, the address returned by
       this routine will be the same as produced by the C &
       operator, but this is not required in C and might not be
       true of systems with word- rather than byte-oriented
       instructions or systems with segmented address spaces.
       MPI_Get_address is an MPI-2 implementation replacing
       MPI_Address.  It returns an MPI_Aint value, which makes it
       better suited for ABI64.  Currently, the Fortran version
       of this function is implemented only in ABI 64.  This
       routine accepts the following parameters:

       location  Specifies the location in caller memory (choice)

       address   Returns the address of the location (MPI_Aint)

       ierror    Specifies the return code value for successful
                 completion, which is in MPI_SUCCESS.
                 MPI_SUCCESS is defined in the mpif.h file.
