Name: H5Pset_dxpl_mpio
Signature:
  herr_t `H5Pset_dxpl_mpio`( hid_t `dxpl_id`, H5FD_mpio_xfer_t `xfer_mode` )
Purpose:
  Sets data transfer mode.
Description:
  `H5Pset_dxpl_mpio` sets the data transfer property list `dxpl_id` to use transfer mode `xfer_mode`. The property list can then be used to control the I/O transfer mode during data I/O operations.

  Valid transfer modes are as follows:

  `H5FD_MPIO_INDEPENDENT`
    Use independent I/O access (default).
  `H5FD_MPIO_COLLECTIVE`
    Use collective I/O access.

Parameters:

hid_t `dxpl_id` | IN: Data transfer property list identifier.
H5FD_mpio_xfer_t `xfer_mode` | IN: Transfer mode.

Returns:
  Returns a non-negative value if successful. Otherwise returns a negative value.
