MPI_Type_lb - Returns the lower bound of a data type
SYNOPSIS
C:
#include <mpi.h>
int MPI_Type_lb ( datatype, displacement )
MPI_Datatype datatype;
MPI_Aint *displacement;
C++:
#include <mpi.h>
void Datatype::Get_extent(
Aint& lb,
Aint& extent) const
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER datatype, displacement, ierror
CALL MPI_TYPE_LB(datatype, displacement, ierror)
STANDARDS
This release implements the MPI 1.2 standard, as
documented by the MPI Forum in the spring 1997 release of
MPI: A Message Passing Interface Standard.
DESCRIPTION
The MPI_Type_lb routine returns the lower bound of a data
type. This routine accepts the following parameters:
datatype Specifies the data type (handle)
displacement
Returns the displacement of the lower bound from
origin, in bytes (integer)
ierror Specifies the return code value for successful
completion, which is in MPI_SUCCESS.
MPI_SUCCESS is defined in the mpif.h file.
