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.
