windows::basic_random_access

Provides random-access handle functionality.

template<
    typename Executor = any_io_executor>
class basic_random_access_handle :
  public windows::basic_overlapped_handle< any_io_executor >

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.

Name	Description
assign	Assign an existing native handle to the handle.
async_read_some_at	Start an asynchronous read at the specified offset.
async_write_some_at	Start an asynchronous write at the specified offset.
basic_random_access_handle [constructor]	Construct a random-access handle without opening it. — Construct a random-access handle on an existing native handle. — Move-construct a random-access handle from another. — Move-construct a random-access 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 a random-access handle from another. — Move-assign a random-access handle from a handle of another executor type.
read_some_at	Read some data from the handle at the specified offset.
release	Release ownership of the underlying native handle.
write_some_at	Write some data to the handle at the specified offset.

The windows::basic_random_access_handle class provides asynchronous and blocking random-access handle functionality.
