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++ func-
       tions 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.

NAME

       MPI_Type_create_struct - Creates a structured data type.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Type_create_struct(int count, int array_of_blocklengths[],
	    MPI_Aint array_of_displacements[], MPI_Datatype array_of_types[],
	    MPI_Datatype *newtype)

Fortran Syntax (see FORTRAN 77 NOTES)
       INCLUDE 'mpif.h'
       MPI_TYPE_CREATE_STRUCT(COUNT, ARRAY_OF_BLOCKLENGTHS,
		 ARRAY_OF_DISPLACEMENTS, ARRAY_OF_TYPES, NEWTYPE, IERROR)
	    INTEGER   COUNT, ARRAY_OF_BLOCKLENGTHS(*), ARRAY_OF_TYPES(*),
	    INTEGER NEWTYPE, IERROR
	    INTEGER(KIND=MPI_ADDRESS_KIND) ARRAY_OF_DISPLACEMENTS(*)

C++ Syntax
       #include <mpi.h>
       static MPI::Datatype MPI::Datatype::Create_struct(int count,
	    const int array_of_blocklengths[], const MPI::Aint
	    array_of_displacements[], const MPI::Datatype
	    array_of_types[])

INPUT PARAMETERS

       count	 Number of blocks (integer) -- also number of entries in arrays array_of_types, array_of_displacements, and array_of_blocklengths.

       array_of_blocklengths
		 Number of elements in each block (array of integers).

       array_of_displacements
		 Byte displacement of each block (array of integers).

       array_of_types
		 Type of elements in each block (array of handles to data-type objects).

OUTPUT PARAMETERS

       newtype	 New data type (handle).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Type_create_struct creates a structured data type. This routine replaces MPI_Type_struct, which is now deprecated.

       NOTE - This routine replaces MPI_Type_struct, which is deprecated. See the man page MPI_Type_struct(3) for information about that routine.

FORTRAN 77 NOTES
       The  MPI  standard prescribes portable Fortran syntax for the ARRAY_OF_DISPLACEMENTS(*) argument only for Fortran 90.  FORTRAN 77 users may
       use the non-portable syntax

	    INTEGER*MPI_ADDRESS_KIND ARRAY_OF_DISPLACEMENTS(*)

       where MPI_ADDRESS_KIND is a constant defined in mpif.h and gives the length of the declared integer in bytes.

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++ func-
       tions  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.
