NAME
       MPI_Win_post - Starts an RMA exposure epoch for the local window associated with win

SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Win_post(MPI_Group group, int assert, MPI_Win win)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_WIN_POST(GROUP, ASSERT, WIN, IERROR)
	    INTEGER GROUP, ASSERT, WIN, IERROR

C++ Syntax
       #include <mpi.h>
       void MPI::Win::Post(const MPI::Group& group, int assert) const

INPUT PARAMETERS
       group	 The group of origin processes (handle)

       assert	 Program assertion (integer)

       win	 Window object (handle)

OUTPUT PARAMETERS
       IERROR	 Fortran only: Error status (integer).

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 MPI_Win_start. MPI_Win_post does not block.

ERRORS
       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::ERRORS_THROW_EXCEPTIONS, 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 MPI_Win_set_errhandler; the predefined error handler MPI_ERRORS_RETURN 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.
