MPI_Pack - Packs a data type into contiguous memory


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Pack ( inbuf, incount, type, outbuf,
            outcount, position, comm )
            void         *inbuf;
            int           incount;
            MPI_Datatype  type;
            void         *outbuf;
            int           outcount;
            int          *position;
            MPI_Comm      comm;

       C++:

            #include <mpi.h>

            void Datatype::Pack(
            const void*       inbuf,
            int               incount,
            void              *outbuf,
            int               outsize,
            int&              position,
            const Comm        &comm) const

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            <type> INBUF(*), OUTBUF(*)
            INTEGER incount, datatype, outsize, position, comm, ierror

            CALL MPI_PACK(inbuf, incount, datatype, *outbuf, outsize, position, comm, 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 routine packs a data type into contiguous
       memory.  This routine accepts the following parameters;

       inbuf     Specifies the input buffer start (choice)

       incount   Specifies the number of input data items


       type      Specifies the data type of each input data item
                 (handle)

       outcount  Specifies the output buffer size in bytes
                 (integer)

       position  Specifies the current position in the buffer in
                 bytes (integer)

       comm      Specifies the communicator for the packed
                 message (handle)

       outbuf    Returns the output buffer start (choice)

       ierror    Specifies the return code value for successful
                 completion, which is in MPI_SUCCESS.
                 MPI_SUCCESS is defined in the mpif.h file.
