MPI_Win_free_keyval(win_keyval, ierror)
    INTEGER, INTENT(INOUT) :: win_keyval
    INTEGER, OPTIONAL, INTENT(OUT) :: ierror

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.

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.
