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  For­
       tran,  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 val­
       ues to be returned (in C and Fortran; this  error  handler
       is  less  useful in with the C++ MPI bindings.  The prede­
       fined 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++ bind­
       ings 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++,

       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 ).
