MPI_Type_create_extent(3) LAM/MPI MPI_Type_create_extent(3)NAMEMPI_Type_create_extent - Create a resized datatype
SYNOPSIS
#include <mpi.h>
int
MPI_Type_create_resized(MPI_Datatype type, MPI_Aint lb,
MPI_Aint extent, MPI_Datatype *newtype)
INPUT PARAMETERS
type - Inpute datatype
lb - New lower bound of the datatype
extent - New extent of the datatype
OUTPUT PARAMETER
newtype
- New resized type
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
If an error occurs in an MPI function, the current MPI error handler is
called to handle it. By default, this error handler aborts the MPI
job. The error handler may be changed with MPI_Errhandler_set ; the
predefined error handler MPI_ERRORS_RETURN may be used to cause error
values to be returned (in C and Fortran; this error handler is less
useful in with the C++ MPI bindings. The predefined error handler
MPI::ERRORS_THROW_EXCEPTIONS should be used in C++ if the error value
needs to be recovered). Note that MPI does not guarantee that an MPI
program can continue past an error.
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. The C++ bindings for MPI do not return error val‐
ues; instead, error values are communicated by throwing exceptions of
type MPI::Exception (but not by default). Exceptions are only thrown
if the error value is not MPI::SUCCESS .
Note that if the MPI::ERRORS_RETURN handler is set in C++, while MPI
functions will return upon an error, there will be no way to recover
what the actual error value was.
MPI_SUCCESS
- No error; MPI routine completed successfully.
MPI_ERR_TYPE
- Invalid datatype argument. May be an uncommitted MPI_Datatype
(see MPI_Type_commit ).
MPI_ERR_OTHER
- Other error; use MPI_Error_string to get more information
about this error code.
MPI_ERR_INTERN
- An internal error has been detected. This is fatal. Please
send a bug report to the LAM mailing list (see http://www.lam-
mpi.org/contact.php ).

contains the text of both the MPI-1 and MPI-2 standards. These docu‐
ments contain detailed information about each MPI function (most of
which is not duplicated in these man pages).
