NAME

       MPI_Type_size - Returns the number of bytes occupied by entries in a data type.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Type_size(MPI_Datatype datatype, int *size)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_TYPE_SIZE(DATATYPE, SIZE, IERROR)
	    INTEGER   DATATYPE, SIZE, IERROR

C++ Syntax
       #include <mpi.h>
       int Datatype::Get_size() const

INPUT PARAMETER

       datatype  Datatype (handle).

OUTPUT PARAMETERS

       size	 Datatype size (integer).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Type_size  returns the total size, in bytes, of the entries in the type signature associated with datatype; i.e., the total size of the
       data in a message that would be created with this datatype. Entries that occur multiple times in the datatype are counted with their multi-
       plicity.

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_size -	Return the number of bytes occupied by entries in the datatype

SYNOPSIS

       int MPI_Type_size(MPI_Datatype datatype, int *size)

INPUT PARAMETERS

       datatype
	      - datatype (handle)

OUTPUT PARAMETER

       size   - datatype size (integer)

THREAD AND INTERRUPT SAFETY

       This  routine  is  both	thread- and interrupt-safe.  This means that this routine may safely be used by multiple threads and from within a
       signal handler.

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument  list.   ierr
       is  an integer and has the same meaning as the return value of the routine in C.  In Fortran, MPI routines are subroutines, and are invoked
       with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the function and Fortran  routines	in
       the  last  argument.  Before the value is returned, the current MPI error handler is called.  By default, this error handler aborts the MPI
       job.  The error handler may  be	changed  with  MPI_Comm_set_errhandler	(for  communicators),  MPI_File_set_errhandler	(for  files),  and
       MPI_Win_set_errhandler  (for  RMA  windows).   The  MPI-1 routine MPI_Errhandler_set may be used but its use is deprecated.  The predefined
       error handler MPI_ERRORS_RETURN may be used to cause error values to be returned.  Note that MPI does not guarentee that an MPI program can
       continue past an error; however, MPI implementations will attempt to continue whenever possible.

       MPI_SUCCESS
	      - No error; MPI routine completed successfully.
       MPI_ERR_TYPE
	      - Invalid datatype argument.  May be an uncommitted MPI_Datatype (see MPI_Type_commit ).
       MPI_ERR_ARG
	      - Invalid argument.  Some argument is invalid and is not identified by a specific error class (e.g., MPI_ERR_RANK ).
