MPI_Type_lb(3)

NAME
     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.
