#### posix::basic_stream_descriptor::native_handle_type

The native representation of a descriptor.

    typedef basic_descriptor< Executor >::native_handle_type native_handle_type;

###### Types

Name | Description
--- | ---
rebind_executor | Rebinds the descriptor type to another executor.
bytes_readable | IO control command to get the amount of data that can be read without blocking.
executor_type | The type of the executor associated with the object.
lowest_layer_type | A descriptor is always the lowest layer.
native_handle_type | The native representation of a descriptor.
wait_type | Wait types.

###### Member Functions

Name | Description
--- | ---
assign | Assign an existing native descriptor to the descriptor.
async_wait | Asynchronously wait for the descriptor to become ready to read, ready to write, or to have pending error conditions.
basic_descriptor [constructor] | Construct a descriptor without opening it. — Construct a descriptor on an existing native descriptor. — Move-construct a descriptor from another. — Move-construct a basic_descriptor from a descriptor of another executor type.
cancel | Cancel all asynchronous operations associated with the descriptor.
close | Close the descriptor.
get_executor | Get the executor associated with the object.
io_control | Perform an IO control command on the descriptor.
is_open | Determine whether the descriptor is open.
lowest_layer | Get a reference to the lowest layer. — Get a const reference to the lowest layer.
native_handle | Get the native descriptor representation.
native_non_blocking | Gets the non-blocking mode of the native descriptor implementation. — Sets the non-blocking mode of the native descriptor implementation.
non_blocking | Gets the non-blocking mode of the descriptor. — Sets the non-blocking mode of the descriptor.
operator= | Move-assign a descriptor from another. — Move-assign a basic_descriptor from a descriptor of another executor type.
release | Release ownership of the native descriptor implementation.
wait | Wait for the descriptor to become ready to read, ready to write, or to have pending error conditions.

###### Protected Member Functions

Name | Description
--- | ---
~basic_descriptor [destructor] | Protected destructor to prevent deletion through this type.

The `posix::basic_descriptor` class template provides the ability to wrap a POSIX descriptor.
