Gets the address of a location in memory
int MPI_Address(const void *location, MPI_Aint *address)
- location in caller memory (choice)
- address of location (address integer)
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.
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
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
All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGER
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
- No error; MPI routine completed successfully.
- Other error; use MPI_Error_string to get more information
about this error code.
