Get an instance of the sync wait array and reserve a wait array cell in the instance for waiting for an object. The event of the cell is reset to nonsignalled state. If reserving cell of the instance fails, try to get another new instance until we can reserve an empty cell of it.
- Returns
- the instance found, never NULL.
- Parameters
-
object in: pointer to the object to wait for type in: lock request type file in: file where requested line in: line where requested index out: index of the reserved cell
