windows::random_access

Provides random-access handle functionality.

class random_access_handle :
  public windows::overlapped_handle

Name	Description
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.
cancel	Cancel all asynchronous operations associated with the handle.
close	Close the handle.
get_executor	Get the executor associated with the object.
get_io_context	(Deprecated: Use get_executor().) Get the io_context associated with the object.
get_io_service	(Deprecated: Use get_executor().) Get the io_context 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.
random_access_handle	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.
read_some_at	Read some data from the handle at the specified offset.
write_some_at	Write some data to the handle at the specified offset.

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