posix::stream_descriptor

Typedef for the typical usage of a stream-oriented descriptor.

typedef basic_stream_descriptor stream_descriptor;

Types

Name	Description
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.
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.
service_type	The type of the service that will be used to provide I/O operations.
wait_type	Wait types.

Member Functions

Name	Description
assign	Assign an existing native descriptor to the descriptor.
async_read_some	Start an asynchronous read.
async_wait	Asynchronously wait for the descriptor to become ready to read, ready to write, or to have pending error conditions.
async_write_some	Start an asynchronous write.
basic_stream_descriptor	Construct a basic_stream_descriptor without opening it. Construct a basic_stream_descriptor on an existing native descriptor. Move-construct a basic_stream_descriptor from another.
cancel	Cancel all asynchronous operations associated with the descriptor.
close	Close the descriptor.
get_executor	Get the executor associated with the object.
get_io_service	(Deprecated: Use get_executor().) 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_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_stream_descriptor from another.
read_some	Read some data from the descriptor.
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.
write_some	Write some data to the descriptor.

Protected Member Functions

Name	Description
get_implementation	Get the underlying implementation of the I/O object.
get_service	Get the service associated with the I/O object.

The posix::basic_stream_descriptor class template provides asynchronous and blocking stream-oriented descriptor functionality.
