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.
