MPI_PACK(3)MPI_PACK(3)NAMEMPI_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;
Page 1
MPI_PACK(3)MPI_PACK(3)
inbuf Specifies the input buffer start (choice)
incount Specifies the number of input data items (integer)
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.
