MPI_Pack_size - Returns the upper bound on the amount of
space needed to 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
ierror Specifies the return code value for successful
completion, which is in MPI_SUCCESS.
MPI_SUCCESS is defined in the mpif.h file.
