MPI_Address - Gets the address of a location in memory
SYNOPSIS
C:
#include <mpi.h>
int MPI_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 address, ierror
CALL MPI_ADDRESS(location, address, ierror)
STANDARDS
This release implements the MPI 1.2 standard, as
documented by the MPI Forum in the spring 1997 release of
MPI: A Message Passing Interface Standard.
DESCRIPTION
The MPI_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.
This routine accepts the following parameters:
location Specifies the location in caller memory (choice)
address Returns the address of the location (integer)
ierror Specifies the return code value for successful
completion, which is in MPI_SUCCESS.
MPI_SUCCESS is defined in the mpif.h file.
