/*@
MPI_Win_get_info - Returns a new info object containing the hints of the window
associated with win.
The current setting of all hints actually used by the system related to this
window is returned in info_used. If no such hints exist, a handle to a newly
created info object is returned that contains no key/value pair. The user is
responsible for freeing info_used via 'MPI_Info_free'.
Input Parameters:
. win - window object (handle)
Output Parameters:
. info_used - new info argument (handle)
Notes:
The info object returned in info_used will contain all hints currently active
for this window. This set of hints may be greater or smaller than the set of
hints specified when the window was created, as the system may not recognize
some hints set by the user, and may recognize other hints that the user has not
set.

/*@
MPI_Neighbor_alltoall - In this function, each process i receives data items
from each process j if an edge (j,i) exists in the topology graph or Cartesian
topology. Similarly, each process i sends data items to all processes j where an
edge (i,j) exists. This call is more general than MPI_NEIGHBOR_ALLGATHER in that
different data items can be sent to each neighbor. The k-th block in send buffer
is sent to the k-th neighboring process and the l-th block in the receive buffer
is received from the l-th neighbor.
Input Parameters:
+ sendbuf - starting address of the send buffer (choice)
. sendcount - number of elements sent to each neighbor (non-negative integer)
. sendtype - data type of send buffer elements (handle)
. recvcount - number of elements received from each neighbor (non-negative integer)
. recvtype - data type of receive buffer elements (handle)
- comm - communicator (handle)
