MPI_Unpack(3)

NAME
     MPI_Unpack - Unpacks a data type into contiguous memory

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Unpack ( inbuf, insize, position, outbuf,
          outcount, type, comm )
          void         *inbuf;
          int           insize;
          int          *position;
          void         *outbuf;
          int           outcount;
          MPI_Datatype  type;
          MPI_Comm      comm;


     C++:

          #include <mpi.h>

          void Datatype::Unpack(
          const void*       inbuf,
          int               insize,
          void              *outbuf,
          int               outcount,
          int&              position,
          const Comm&       comm) const


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          <type> INBUF(*), OUTBUF(*)
          INTEGER insize, position, outcount, datatype, comm, ierror

          CALL MPI_UNPACK(inbuf, insize, position, outbuf, outcount, datatype, 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_Unpack routine unpacks a data type into contiguous memory.  This
     routine accepts the following parameters:
     inbuf          Specifies the input buffer start (choice)

     insize         Specifies the size of input buffer in bytes (integer)

     position       Specifies the current position in bytes (integer)

     outcount       Specifies the number of items to be unpacked (integer)

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

     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.
