posix::basic_descriptor

Provides POSIX descriptor functionality.

template<
    typename DescriptorService>
class basic_descriptor :
  public basic_io_object< DescriptorService >,
  public posix::descriptor_base

Name	Description
bytes_readable	IO control command to get the amount of data that can be read without blocking.
implementation_type	The underlying implementation type of I/O object.
lowest_layer_type	A basic_descriptor is always the lowest layer.
native_handle_type	The native representation of a descriptor.
native_type	(Deprecated: Use native_handle_type.) The native representation of a descriptor.
non_blocking_io	(Deprecated: Use non_blocking().) IO control command to set the blocking mode of the descriptor.
service_type	The type of the service that will be used to provide I/O operations.

Name	Description
assign	Assign an existing native descriptor to the descriptor.
basic_descriptor	Construct a basic_descriptor without opening it. Construct a basic_descriptor on an existing native descriptor. Move-construct a basic_descriptor from another.
cancel	Cancel all asynchronous operations associated with the descriptor.
close	Close the descriptor.
get_io_service	Get the io_service 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	(Deprecated: Use native_handle().) Get the native descriptor representation.
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 basic_descriptor from another.
release	Release ownership of the native descriptor implementation.

Name	Description
get_implementation	Get the underlying implementation of the I/O object.
get_service	Get the service associated with the I/O object.
~basic_descriptor	Protected destructor to prevent deletion through this type.

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