pack a message
SYNOPSIS
C:
#include <mpi.h>
int MPI_Pack_size ( incount, datatype, comm, size )
int incount;
MPI_Datatype datatype;
MPI_Comm comm;
int *size;
C++:
#include <mpi.h>
int Datatype::Pack_size(
int incount,
const Comm& comm) const
Fortran:
INCLUDE "mpif.h" (or USE MPI)
INTEGER incount, datatype, comm, size, ierror
CALL MPI_PACK_SIZE(incount, datatype, comm, size, 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_Pack_size routine returns the upper bound on the amount of space
needed to pack a message. This routine accepts the following parameters:
incount Specifies the count argument to the packing call (integer)
datatype Specifies the data type argument to the packing call (handle)
comm Specifies the communicator argument to the packing call
(handle)

size Returns the upper bound on the size of the packed message 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.
