MPI_Win_post(3OpenMPI)                                                                MPI_Win_post(3OpenMPI)



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.
