Routines for packing data

Packing Data

To pack data:

  mpi_pack (inbuf, incount, datatype,
            outbuf, outsize, position,
            comm, ierr)

This takes incount items of specified datatype from buffer inbuf and packs them into outbuf starting at offset position.

• The offset position is specified in bytes.
• On return position is set to the next location in outbuf
