MPI_Get_address(3)							MPI							MPI_Get_address(3)

NAME

       MPI_Get_address -  Get the address of a location in memory

SYNOPSIS

       int MPI_Get_address(void *location, MPI_Aint *address)

INPUT PARAMETER

       location
	      - location in caller memory (choice)

OUTPUT PARAMETER

       address
	      - address of location (address integer)

NOTES

       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  instruc-
       tions or systems with segmented address spaces.

       This routine should be used instead of MPI_Address .

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.

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.

       In Fortran, the integer type is always signed.  This can cause problems on systems where the address fits into a four byte unsigned integer
       but  the  value is larger than the largest signed integer.  For example, a system with more than 2 GBytes of memory may have addresses that
       do not fit within a four byte signed integer.  Unfortunately, there is no easy solution to this problem, as there is  no  Fortran  datatype
       that can be used here (using a longer integer type will cause other problems, as well as surprising users when the size of the integer type
       is larger that the size of a pointer in C).  In this case, it is recommended that you use C to manipulate addresses.

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.

NAME

       MPI_Win_create_errhandler -  Create an error handler for use with MPI window objects

SYNOPSIS

       int MPI_Win_create_errhandler(MPI_Win_errhandler_fn *function,
				   MPI_Errhandler *errhandler)

INPUT PARAMETER

       function
	      - user defined error handling procedure (function)

OUTPUT PARAMETER

       errhandler
	      - MPI error handler (handle)

THREAD AND INTERRUPT SAFETY

       This  routine  is  thread-safe.	This means that this routine may be safely used by multiple threads without the need for any user-provided
       thread locks.  However, the routine is not interrupt safe.  Typically, this is due to the use of memory allocation routines such as  malloc
       or other non-MPICH runtime routines that are themselves not interrupt-safe.

       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
