windows::basic_random_access_handle

Provides random-access handle functionality.

template<
    typename RandomAccessHandleService = random_access_handle_service>
class basic_random_access_handle :
  public windows::basic_handle< RandomAccessHandleService >

Types

Name	Description
implementation_type	The underlying implementation type of I/O object.
lowest_layer_type	A basic_handle is always the lowest layer.
native_handle_type	The native representation of a handle.
native_type	(Deprecated: Use native_handle_type.) The native representation of a handle.
service_type	The type of the service that will be used to provide I/O operations.

Member Functions

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	Construct a basic_random_access_handle without opening it. Construct a basic_random_access_handle on an existing native handle. Move-construct a basic_random_access_handle from another.
cancel	Cancel all asynchronous operations associated with the handle.
close	Close the handle.
get_io_service	Get the io_service 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	(Deprecated: Use native_handle().) Get the native handle representation.
native_handle	Get the native handle representation.
operator=	Move-assign a basic_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.

Protected Member Functions

Name	Description
get_implementation	Get the underlying implementation of the I/O object.
get_service	Get the service associated with the I/O object.

Protected Data Members

Name	Description
implementation	(Deprecated: Use get_implementation().) The underlying implementation of the I/O object.
service	(Deprecated: Use get_service().) The service associated with the I/O object.

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