Types

Name

Description

executor_type

The type of the executor associated with the object.

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.

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_wait

Start an asynchronous wait on the object handle.

basic_object_handle

Construct a basic_object_handle without opening it.

Construct a basic_object_handle on an existing native handle.

Move-construct a basic_object_handle from another.

cancel

Cancel all asynchronous operations associated with the handle.

close

Close the handle.

get_executor

Get the executor associated with the object.

get_io_service

(Deprecated: Use get_executor().) 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_handle

Get the native handle representation.

operator=

Protected Member Functions

Name

Description

get_implementation
