*
* Programmer: rky 980813
*
* Notes:
* For collective data transfer only since this would eventually call
* H5FD_mpio_setup to do setup to eveually call MPI_File_set_view in
* H5FD_mpio_read or H5FD_mpio_write. MPI_File_set_view is a collective
* call. Letting independent data transfer use this route would result in
* hanging.
*
* The preconditions for calling this routine are located in the
* H5S_mpio_opt_possible() routine, which determines whether this routine
* can be called for a given dataset transfer.
*
* Modifications:
* rky 980918
* Added must_convert parameter to let caller know we can't optimize
* the xfer.
*
* Albert Cheng, 001123
* Include the MPI_type freeing as part of cleanup code.
*
* QAK - 2002/04/02
* Removed the must_convert parameter and move preconditions to
* H5S_mpio_opt_possible() routine
*
* QAK - 2002/06/17
* Removed 'disp' parameter from H5FD_mpio_setup routine and use the
* address of the dataset in MPI_File_set_view() calls, as necessary.
*
* QAK - 2002/06/18
* Removed 'dc_plist' parameter, since it was not used. Also, switch to
* getting the 'extra_offset' setting for each selection.

NAME
H5O_attr_decode
PURPOSE
Decode a attribute message and return a pointer to a memory struct
with the decoded information
USAGE
void *H5O_attr_decode(f, raw_size, p)
H5F_t *f; IN: pointer to the HDF5 file struct
size_t raw_size; IN: size of the raw information buffer
const uint8_t *p; IN: the raw information buffer
RETURNS
Pointer to the new message in native order on success, NULL on failure
DESCRIPTION
This function decodes the "raw" disk form of a attribute message
into a struct in memory native format. The struct is allocated within this
function using malloc() and is returned to the caller.
