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++ functions 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.
