MPI_Type_create_indexed_block(3OpenMPI)                              MPI_Type_create_indexed_block(3OpenMPI)



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.
