H5Pget_fapl_mpiposix

)
H5FD_MPIPOSIX
driver, H5Pget_fapl_mpiposix
returns
the MPI communicator through the comm
pointer, if those values are non-null.
comm
is not copied, so it is valid only
until the file access property list is either modified or closed.
use_gpfs_hints
specifies whether to attempt to use
GPFS hints when accessing this file.
A value of TRUE
(or 1
) indicates that
the hints are being used, where possible.
A value of FALSE
(or 0
) indicates that
the hints are not being used.
hid_t fapl_id |
IN: File access property list identifier. |
MPI_Comm *comm |
