NAME

       MPI_Win_post  - Starts an RMA exposure epoch for the local window asso-
       ciated 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.
