DESCRIPTION
       Starts an RMA exposure epoch for the local window associated with  win.
       Only the processes belonging to group should access the window with RMA
       calls on win during this epoch. Each process  in  group  must  issue  a
       matching call to MPIWinstart. MPIWinpost does not block.


EERRRROORRSS
       Almost  all MPI routines return an error value; C routines as the value
       of the function and Fortran routines in the last  argument.  C++  func-
       tions  do  not  return  errors.  If the default error handler is set to
       MPI::ERRORSTHROWEXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.

       Before  the  error  value is returned, the current MPI error handler is
       called. By default, this error handler aborts the MPI job,  except  for
       I/O   function   errors.   The   error  handler  may  be  changed  with
       MPIWinseterrhandler; the predefined error handler  MPIERRORSRETURN
       may  be  used  to cause error values to be returned. Note that MPI does
       not guarantee that an MPI program can continue past an error.
