MPI_Win_delete_attr_function is a placeholder for the application-defined function name. This is a delete callback function for win_keyval.

Syntax

int MPI_Win_delete_attr_function(
           MPI_Win win,
           int     win_keyval,
  _In_     void    *attribute_val,
  _In_opt_ void    *extra_state
);

Parameters

win
MPI window object.
win_keyval
Window key value.
attribute_val [in]
Attribute value.
extra_state [in, optional]
Extra state.

Return value

If an attribute delete function returns anything other than MPI_SUCCESS, then the call that caused it to be invoked (for example, MPI_Win_free), is erroneous.
