NAME

       MPI_Type_create_hvector - Creates a vector (strided) data type with offset in bytes.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Type_create_hvector(int count, int blocklength,
	    MPI_Aint stride, MPI_Datatype oldtype, MPI_Datatype *newtype)

Fortran Syntax (see FORTRAN 77 NOTES)
       INCLUDE 'mpif.h'
       MPI_TYPE_CREATE_HVECTOR(COUNT, BLOCKLENGTH, STRIDE, OLDTYPE,
	    NEWTYPE, IERROR)

	    INTEGER   COUNT, BLOCKLENGTH, OLDTYPE, NEWTYPE, IERROR
	    INTEGER(KIND=MPI_ADDRESS_KIND) STRIDE

C++ Syntax
       #include <mpi.h>
       MPI::Datatype MPI::Datatype::Create_hvector(int count,
	    int blocklength, MPI::Aint stride) const

INPUT PARAMETERS

       count	 Number of blocks (nonnegative integer).

       blocklength
		 Number of elements in each block (nonnegative integer).

       stride	 Number of bytes between start of each block (integer).

       oldtype	 Old data type (handle).

OUTPUT PARAMETERS

       newtype	 New data type (handle).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Type_create_hvector creates a vector (strided) data type with offset in bytes.

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

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

	    INTEGER*MPI_ADDRESS_KIND STRIDE

       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.

NAME

       MPI_Type_create_resized - Returns a new data type with new extent and upper and lower bounds.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Type_create_resized(MPI_Datatype oldtype, MPI_Aint lb,
	    MPI_Aint extent, MPI_Datatype *newtype)

Fortran Syntax (see FORTRAN 77 NOTES)
       INCLUDE 'mpif.h'
       MPI_TYPE_CREATE_RESIZED(OLDTYPE, LB, EXTENT, NEWTYPE, IERROR)
	    INTEGER   OLDTYPE, NEWTYPE, IERROR
	    INTEGER(KIND=MPI_ADDRESS_KIND)     LB, EXTENT

C++ Syntax
       #include <mpi.h>
       MPI::Datatype MPI::Datatype::Create_resized(const MPI::Aint lb,
	    const MPI::Aint extent) const

INPUT PARAMETERS

       oldtype	 Input data type (handle).

       lb	 New lower bound of data type (integer).

       extent	 New extent of data type (integer).

OUTPUT PARAMETERS

       newtype	 Output data type (handle).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Type_create_resized	returns  in  newtype a handle to a new data type that is identical to oldtype, except that the lower bound of this
       new data type is set to be lb, and its upper bound is set to be lb + extent. Any previous lb and ub markers are erased, and a new  pair	of
       lower  bound  and  upper  bound markers are put in the positions indicated by the lb and extent arguments. This affects the behavior of the
       data type when used in communication operations, with count > 1, and when used in the construction of new derived data types.

FORTRAN 77 NOTES
       The MPI standard prescribes portable Fortran syntax for the LB and EXTENT arguments only for Fortran 90. FORTRAN 77 users may use the  non-
       portable syntax

	    INTEGER*MPI_ADDRESS_KIND LB
       or
	    INTEGER*MPI_ADDRESS_KIND EXTENT

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

NOTE

       Use of MPI_Type_create_resized is strongly recommended over the old MPI-1 functions MPI_Type_extent and MPI_Type_lb.

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.
