Typedef for the typical usage of an overlapped handle.

    typedef basic_overlapped_handle overlapped_handle;

##### Types

Name | Description
--- | ---
rebind_executor | Rebinds the handle type to another executor.
executor_type | The type of the executor associated with the object.
lowest_layer_type | An overlapped_handle is always the lowest layer.
native_handle_type | The native representation of a handle.

##### Member Functions

Name | Description
--- | ---
assign | Assign an existing native handle to the handle.
basic_overlapped_handle [constructor] | Construct an overlapped handle without opening it. — Construct an overlapped handle on an existing native handle. — Move-construct an overlapped handle from another. — Move-construct an overlapped handle from a handle of another executor type.
cancel | Cancel all asynchronous operations associated with the handle.
close | Close the handle.
get_executor | Get the executor associated with the object.
is_open | Determine whether the handle is open.
lowest_layer | Get a reference to the lowest layer. — Get a const reference to the lowest layer.
native_handle | Get the native handle representation.
operator= | Move-assign an overlapped handle from another. — Move-assign an overlapped handle from a handle of another executor type.
release | Release ownership of the underlying native handle.

##### Protected Member Functions

Name | Description
--- | ---
~basic_overlapped_handle [destructor] | Protected destructor to prevent deletion through this type.
