NAME

       MPI_Win_free_keyval - Frees a window keyval.

SYNTAX


C Syntax

       #include <mpi.h>
       int MPI_Win_free_keyval(int *win_keyval)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_WIN_FREE_KEYVAL(WIN_KEYVAL, IERROR)
            INTEGER WIN_KEYVAL, IERROR

C++ Syntax

       #include <mpi.h>
       static void MPI::Win::Free_keyval(int& win_keyval)

INPUT/OUTPUT PARAMETER

       win_keyval
                 Key value (integer).

OUTPUT PARAMETER

       IERROR    Fortran only: Error status (integer).

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.
