NAME

       MPI_Type_create_indexed_block  -  Creates  an indexed data type with the same block length
       for all blocks.

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Type_create_indexed_block(int count, int blocklength, int array_of_displacements[], MPI_Datatype oldtype, MPI_Datatype *newtype)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_TYPE_CREATE_INDEXED_BLOCK(COUNT, BLOCKLENGTH,
                 ARRAY_OF_DISPLACEMENTS, OLDTYPE, NEWTYPE, IERROR)
            INTEGER   COUNT, BLOCKLENGTH, ARRAY_OF_DISPLACEMENTS(*),
                    OLDTYPE, NEWTYPE, IERROR

C++ Syntax

       #include <mpi.h>
       MPI::Datatype MPI::Datatype::Create_indexed_block( int count,
            int blocklength, const int array_of_displacements[]) const

INPUT PARAMETERS

       count     Length of array of displacements (integer).

       blocklength
                 Size of block (integer).

       array_of_displacements
                 Array of displacements (array of integers).

       oldtype   Old data type (handle).

OUTPUT PARAMETERS

       newtype   New data type (handle).

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_Type_create_indexed_block creates an indexed data type with the same block length  for
       all blocks.

ERRORS

       Almost all MPI routines return an error value; C routines as the value of the function and
       Fortran routines in the last argument. C++ functions do not return errors. If the  default
       error  handler  is  set  to  MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception
       mechanism will be used to throw an MPI:Exception object.

       Before the error value is returned, the current MPI error handler is called.  By  default,
       this  error  handler aborts the MPI job, except for I/O function errors. The error handler
       may   be   changed   with   MPI_Comm_set_errhandler;   the   predefined   error    handler
       MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not
       guarantee that an MPI program can continue past an error.
