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_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

Protected Data Members

Name

Description

implementation

(Deprecated: Use get_implementation().) The underlying implementation of the I/O object.

service
