typedef basic_random_access_handle random_access_handle;
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_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.

cancel

Cancel all asynchronous operations associated with the handle.

close

Close the handle.

get_io_service

io_service

(Deprecated: use 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

write_some_at

Write some data to the handle at the specified offset.

Protected Data Members

Name

Description

implementation
