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 off-
set in bytes.
NOTE - This routine replaces MPI_Type_hvector, which is deprecated. See
the man page MPI_Type_hvector(3) for information about that routine.
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-porta-
ble syntax
INTEGER*MPI_ADDRESS_KIND STRIDE
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.
