The new functions for caching on windows are:
| MPI_WIN_CREATE_KEYVAL(win_copy_attr_fn, win_delete_attr_fn, win_keyval, extra_state) | |
| IN win_copy_attr_fn | copy callback function for win_keyval (function) |
| IN win_delete_attr_fn | delete callback function for win_keyval (function) |
| OUT win_keyval | key value for future access (integer) |
| IN extra_state | extra state for callback functions |
int MPI_Win_create_keyval(MPI_Win_copy_attr_function *win_copy_attr_fn, MPI_Win_delete_attr_function *win_delete_attr_fn, int *win_keyval, void *extra_state)

static int MPI::Win::Create_keyval(MPI::Win::Copy_attr_function* win_copy_attr_fn, MPI::Win::Delete_attr_function* win_delete_attr_fn, void* extra_state)
The argument win_copy_attr_fn may be specified as MPI_WIN_NULL_COPY_FN or MPI_WIN_DUP_FN from either C, C++, or Fortran. MPI_WIN_NULL_COPY_FN is a function that does nothing other than returning flag = 0 and MPI_SUCCESS. MPI_WIN_DUP_FN is a simple-minded copy function that sets flag = 1, returns the value of attribute_val_in in attribute_val_out, and returns MPI_SUCCESS.
The argument win_delete_attr_fn may be specified as MPI_WIN_NULL_DELETE_FN from either C, C++, or Fortran. MPI_WIN_NULL_DELETE_FN is a function that does nothing, other than returning MPI_SUCCESS.
The C callback functions are:
typedef int MPI_Win_copy_attr_function(MPI_Win oldwin, int win_keyval, void *extra_state, void *attribute_val_in, void *attribute_val_out, int *flag);
and
typedef int MPI_Win_delete_attr_function(MPI_Win win, int win_keyval, void *attribute_val, void *extra_state);
The Fortran callback functions are:
SUBROUTINE WIN_COPY_ATTR_FN(OLDWIN, WIN_KEYVAL, EXTRA_STATE, ATTRIBUTE_VAL_IN, ATTRIBUTE_VAL_OUT, FLAG, IERROR)
INTEGER OLDWIN, WIN_KEYVAL, IERROR
INTEGER(KIND=MPI_ADDRESS_KIND) EXTRA_STATE, ATTRIBUTE_VAL_IN,
ATTRIBUTE_VAL_OUT
LOGICAL FLAG
and
SUBROUTINE WIN_DELETE_ATTR_FN(WIN, WIN_KEYVAL, ATTRIBUTE_VAL, EXTRA_STATE, IERROR)
INTEGER WIN, WIN_KEYVAL, IERROR
INTEGER(KIND=MPI_ADDRESS_KIND) ATTRIBUTE_VAL, EXTRA_STATE
The C++ callbacks are:
typedef int MPI::Win::Copy_attr_function(const MPI::Win& oldwin, int win_keyval, void* extra_state, void* attribute_val_in, void* attribute_val_out, bool& flag);
and
typedef int MPI::Win::Delete_attr_function(MPI::Win& win, int win_keyval, void* attribute_val, void* extra_state);
If an attribute copy function or attribute delete function returns other than
MPI_SUCCESS, then the call that caused it to be invoked (for example,
MPI_WIN_FREE), is erroneous.
