       MPI_Address  -  Gets the address of a location in memory -- use of this
       routine is deprecated.


C Syntax

       #include <mpi.h>
       int MPI_Address(void *location, MPI_Aint *address)

Fortran Syntax

       INCLUDE 'mpif.h'
            <type>    LOCATION (*)


       location  Location in caller memory (choice).


       address   Address of location (integer).

       IERROR    Fortran only: Error status (integer).


       Note that use of this routine is deprecated as  of  MPI-2.  Please  use
       MPI_get_address instead.

       This deprecated routine is not available in C++.

       The address of a location in memory can be found by invoking this func-
       tion. Returns the (byte) address of location.

       Example: Using MPI_Address for an array.

       REAL A(100,100)
          INTEGER I1, I2, DIFF
          CALL MPI_ADDRESS(A(1,1), I1, IERROR)
          CALL MPI_ADDRESS(A(10,10), I2, IERROR)
          DIFF = I2 - I1
       ! The value of DIFF is 909*sizeofreal; the values of I1 and I2 are
       ! implementation dependent.


       This routine is provided for both Fortran and C programmers and may  be
       useful  when writing portable code. In the current release, the address
       returned by this routine will be the same as that produced by the  C  &

       C  users  may  be  tempted  to  avoid using MPI_Address and rely on the
       availability of the address operator &.  Note, however,  that  &  cast-
       expression  is a pointer, not an address.  ANSI C does not require that
       Almost all MPI routines return an error value; C routines as the  value
       of  the  function  and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default  error  handler  is  set  to
       MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.

       Before the error value is returned, the current MPI  error  handler  is
       called.  By  default, this error handler aborts the MPI job, except for
       I/O  function  errors.  The  error  handler   may   be   changed   with
       MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN
       may be used to cause error values to be returned. Note  that  MPI  does
       not guarantee that an MPI program can continue past an error.
