MPI_Win_free_keyval(3)             Open MPI             MPI_Win_free_keyval(3)



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++
       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_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.
