MPI_Type_create_extent(3)					      LAM/MPI						 MPI_Type_create_extent(3)

NAME

       MPI_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 values; 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 ).

MORE INFORMATION

       For  more  information,	please	see the official MPI Forum web site, which contains the text of both the MPI-1 and MPI-2 standards.  These
       documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).
