NAME

       MPI_Win_free - Frees the window object and returns a null handle.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Win_free(MPI_Win *win)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_WIN_FREE(WIN, IERROR)
	    INTEGER WIN, IERROR

C++ Syntax
       #include <mpi.h>
       void MPI::Win::Free()

INPUT
/OUTPUT PARAMETER
       win	 Window object (handle).

OUTPUT PARAMETER

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Win_free  frees  the  window object win and returns a null handle (equal to MPI_WIN_NULL). This collective call is executed by all pro-
       cesses in the group associated with win. It can be invoked by a process only after it has completed its involvement in  RMA  communications
       on  window  win, that is, the process has called MPI_Win_fence, or called MPI_Win_unlock to match a previous call to MPI_Win_lock. When the
       call returns, the window memory can be freed.

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_Comm_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.
