NAME

       MPI_Address -  Gets the address of a location in memory

SYNOPSIS

       int MPI_Address(void *location, MPI_Aint *address)

INPUT PARAMETERS

       location
              - location in caller memory (choice)

OUTPUT PARAMETERS

       address
              - address of location (address integer)

NOTE

       This  routine  is provided for both the 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  may
       not  be  true  of  systems  with  word-  rather than byte-oriented instructions or systems with segmented
       address spaces.

THREAD AND INTERRUPT SAFETY

       This routine is both thread- and interrupt-safe.  This means that this routine  may  safely  be  used  by
       multiple threads and from within a signal handler.

DEPRECATED FUNCTION

       The  MPI-2 standard deprecated a number of routines because MPI-2 provides better versions.  This routine
       is one of those that was deprecated.  The routine may continue to be used, but new code  should  use  the
       replacement routine.  The replacement for this routine is MPI_Get_address .

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

       All  MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the
       function and Fortran routines in the last argument.  Before the value is returned, the current MPI  error
       handler  is called.  By default, this error handler aborts the MPI job.  The error handler may be changed
       with   MPI_Comm_set_errhandler   (for   communicators),   MPI_File_set_errhandler   (for   files),    and
       MPI_Win_set_errhandler  (for  RMA windows).  The MPI-1 routine MPI_Errhandler_set may be used but its use
       is deprecated.  The predefined error handler MPI_ERRORS_RETURN may be used to cause error  values  to  be
       returned.   Note that MPI does not guarentee that an MPI program can continue past an error; however, MPI
       implementations will attempt to continue whenever possible.

       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_ERR_OTHER
              - Other error; use MPI_Error_string to get more information about this error code.
