+/// Provides waitable timer functionality.
+/**
+ * The basic_deadline_timer class template provides the ability to perform a
+ * blocking or asynchronous wait for a timer to expire.
+ *
+ * Most applications will use the boost::asio::deadline_timer typedef.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * @par Examples
+ * Performing a blocking wait:
+ * @code
+ * // Construct a timer without setting an expiry time.
+ * boost::asio::deadline_timer timer(io_service);
+ *
+ * // Set an expiry time relative to now.
+ * timer.expires_from_now(boost::posix_time::seconds(5));
+ *
+ * // Wait for the timer to expire.
+ * timer.wait();
+ * @endcode
+ *
+ * @par
+ * Performing an asynchronous wait:
+ * @code
+ * void handler(const boost::system::error_code& error)
+ * {
+ * if (!error)
+ * {
+ * // Timer expired.
+ * }
+ * }
+ *
+ * ...
+ *
+ * // Construct a timer with an absolute expiry time.
+ * boost::asio::deadline_timer timer(io_service,
+ * boost::posix_time::time_from_string("2005-12-07 23:59:59.000"));
+ *
+ * // Start an asynchronous wait.
+ * timer.async_wait(handler);
+ * @endcode
+ *
+ * @par Changing an active deadline_timer's expiry time
+ *
+ * Changing the expiry time of a timer while there are pending asynchronous
+ * waits causes those wait operations to be cancelled. To ensure that the action
+ * associated with the timer is performed only once, use something like this:
+ * used:
+ *
+ * @code
+ * void on_some_event()
+ * {
+ * if (my_timer.expires_from_now(seconds(5)) > 0)
+ * {
+ * // We managed to cancel the timer. Start new asynchronous wait.
+ * my_timer.async_wait(on_timeout);
+ * }
+ * else
+ * {
+ * // Too late, timer has already expired!
+ * }
+ * }
+ *
+ * void on_timeout(const boost::system::error_code& e)
+ * {
+ * if (e != boost::asio::error::operation_aborted)
+ * {
+ * // Timer was not cancelled, take necessary action.
+ * }
+ * }
+ * @endcode
+ *
+ * @li The boost::asio::basic_deadline_timer::expires_from_now() function
+ * cancels any pending asynchronous waits, and returns the number of
+ * asynchronous waits that were cancelled. If it returns 0 then you were too
+ * late and the wait handler has already been executed, or will soon be
+ * executed. If it returns 1 then the wait handler was successfully cancelled.
+ *
+ * @li If a wait handler is cancelled, the boost::system::error_code passed to
+ * it contains the value boost::asio::error::operation_aborted.

+/// Automatically resizable buffer class based on std::streambuf.
+/**
+ * The @c basic_streambuf class is derived from @c std::streambuf to associate
+ * the streambuf's input and output sequences with one or more character
+ * arrays. These character arrays are internal to the @c basic_streambuf
+ * object, but direct access to the array elements is provided to permit them
+ * to be used efficiently with I/O operations. Characters written to the output
+ * sequence of a @c basic_streambuf object are appended to the input sequence
+ * of the same object.
+ *
+ * The @c basic_streambuf class's public interface is intended to permit the
+ * following implementation strategies:
+ *
+ * @li A single contiguous character array, which is reallocated as necessary
+ * to accommodate changes in the size of the character sequence. This is the
+ * implementation approach currently used in Asio.
+ *
+ * @li A sequence of one or more character arrays, where each array is of the
+ * same size. Additional character array objects are appended to the sequence
+ * to accommodate changes in the size of the character sequence.
+ *
+ * @li A sequence of one or more character arrays of varying sizes. Additional
+ * character array objects are appended to the sequence to accommodate changes
+ * in the size of the character sequence.
+ *
+ * The constructor for basic_streambuf accepts a @c size_t argument specifying
+ * the maximum of the sum of the sizes of the input sequence and output
+ * sequence. During the lifetime of the @c basic_streambuf object, the following
+ * invariant holds:
+ * @code size() <= max_size()@endcode
+ * Any member function that would, if successful, cause the invariant to be
+ * violated shall throw an exception of class @c std::length_error.
+ *
+ * The constructor for @c basic_streambuf takes an Allocator argument. A copy
+ * of this argument is used for any memory allocation performed, by the
+ * constructor and by all member functions, during the lifetime of each @c
+ * basic_streambuf object.
+ *
+ * @par Examples
+ * Writing directly from an streambuf to a socket:
+ * @code
+ * boost::asio::streambuf b;
+ * std::ostream os(&b);
+ * os << "Hello, World!\n";
+ *
+ * // try sending some data in input sequence
+ * size_t n = sock.send(b.data());
+ *
+ * b.consume(n); // sent data is removed from input sequence
+ * @endcode
+ *
+ * Reading from a socket directly into a streambuf:
+ * @code
+ * boost::asio::streambuf b;
+ *
+ * // reserve 512 bytes in output sequence
+ * boost::asio::streambuf::const_buffers_type bufs = b.prepare(512);
+ *
+ * size_t n = sock.receive(bufs);
+ *
+ * // received data is "committed" from output sequence to input sequence
+ * b.commit(n);
+ *
+ * std::istream is(&b);
+ * std::string s;
+ * is >> s;

+/** @defgroup buffer boost::asio::buffer
+ *
+ * @brief The boost::asio::buffer function is used to create a buffer object to
+ * represent raw memory, an array of POD elements, a vector of POD elements,
+ * or a std::string.
+ *
+ * A buffer object represents a contiguous region of memory as a 2-tuple
+ * consisting of a pointer and size in bytes. A tuple of the form <tt>{void*,
+ * size_t}</tt> specifies a mutable (modifiable) region of memory. Similarly, a
+ * tuple of the form <tt>{const void*, size_t}</tt> specifies a const
+ * (non-modifiable) region of memory. These two forms correspond to the classes
+ * mutable_buffer and const_buffer, respectively. To mirror C++'s conversion
+ * rules, a mutable_buffer is implicitly convertible to a const_buffer, and the
+ * opposite conversion is not permitted.
+ *
+ * The simplest use case involves reading or writing a single buffer of a
+ * specified size:
+ *
+ * @code sock.send(boost::asio::buffer(data, size)); @endcode
+ *
+ * In the above example, the return value of boost::asio::buffer meets the
+ * requirements of the ConstBufferSequence concept so that it may be directly
+ * passed to the socket's write function. A buffer created for modifiable
+ * memory also meets the requirements of the MutableBufferSequence concept.
+ *
+ * An individual buffer may be created from a builtin array, std::vector or
+ * boost::array of POD elements. This helps prevent buffer overruns by
+ * automatically determining the size of the buffer:
+ *
+ * @code char d1[128];
+ * size_t bytes_transferred = sock.receive(boost::asio::buffer(d1));
+ *
+ * std::vector<char> d2(128);
+ * bytes_transferred = sock.receive(boost::asio::buffer(d2));
+ *
+ * boost::array<char, 128> d3;
+ * bytes_transferred = sock.receive(boost::asio::buffer(d3)); @endcode
+ *
+ * In all three cases above, the buffers created are exactly 128 bytes long.
+ * Note that a vector is @e never automatically resized when creating or using
+ * a buffer. The buffer size is determined using the vector's <tt>size()</tt>
+ * member function, and not its capacity.
+ *
+ * @par Accessing Buffer Contents
+ *
+ * The contents of a buffer may be accessed using the boost::asio::buffer_size
+ * and boost::asio::buffer_cast functions:
+ *
+ * @code boost::asio::mutable_buffer b1 = ...;
+ * std::size_t s1 = boost::asio::buffer_size(b1);
+ * unsigned char* p1 = boost::asio::buffer_cast<unsigned char*>(b1);
+ *
+ * boost::asio::const_buffer b2 = ...;
+ * std::size_t s2 = boost::asio::buffer_size(b2);
+ * const void* p2 = boost::asio::buffer_cast<const void*>(b2); @endcode
+ *
+ * The boost::asio::buffer_cast function permits violations of type safety, so
+ * uses of it in application code should be carefully considered.
+ *
+ * @par Buffer Invalidation
+ *
+ * A buffer object does not have any ownership of the memory it refers to. It
+ * is the responsibility of the application to ensure the memory region remains
+ * valid until it is no longer required for an I/O operation. When the memory
+ * is no longer available, the buffer is said to have been invalidated.
+ *
+ * For the boost::asio::buffer overloads that accept an argument of type
+ * std::vector, the buffer objects returned are invalidated by any vector
+ * operation that also invalidates all references, pointers and iterators
+ * referring to the elements in the sequence (C++ Std, 23.2.4)
+ *
+ * For the boost::asio::buffer overloads that accept an argument of type
+ * std::string, the buffer objects returned are invalidated according to the
+ * rules defined for invalidation of references, pointers and iterators
+ * referring to elements of the sequence (C++ Std, 21.3).
+ *
+ * @par Buffer Arithmetic
+ *
+ * Buffer objects may be manipulated using simple arithmetic in a safe way
+ * which helps prevent buffer overruns. Consider an array initialised as
+ * follows:
+ *
+ * @code boost::array<char, 6> a = { 'a', 'b', 'c', 'd', 'e' }; @endcode
+ *
+ * A buffer object @c b1 created using:
+ *
+ * @code b1 = boost::asio::buffer(a); @endcode
+ *
+ * represents the entire array, <tt>{ 'a', 'b', 'c', 'd', 'e' }</tt>. An
+ * optional second argument to the boost::asio::buffer function may be used to
+ * limit the size, in bytes, of the buffer:
+ *
+ * @code b2 = boost::asio::buffer(a, 3); @endcode
+ *
+ * such that @c b2 represents the data <tt>{ 'a', 'b', 'c' }</tt>. Even if the
+ * size argument exceeds the actual size of the array, the size of the buffer
+ * object created will be limited to the array size.
+ *
+ * An offset may be applied to an existing buffer to create a new one:
+ *
+ * @code b3 = b1 + 2; @endcode
+ *
+ * where @c b3 will set to represent <tt>{ 'c', 'd', 'e' }</tt>. If the offset
+ * exceeds the size of the existing buffer, the newly created buffer will be
+ * empty.
+ *
+ * Both an offset and size may be specified to create a buffer that corresponds
+ * to a specific range of bytes within an existing buffer:
+ *
+ * @code b4 = boost::asio::buffer(b1 + 1, 3); @endcode
+ *
+ * so that @c b4 will refer to the bytes <tt>{ 'b', 'c', 'd' }</tt>.
+ *
+ * @par Buffers and Scatter-Gather I/O
+ *
+ * To read or write using multiple buffers (i.e. scatter-gather I/O), multiple
+ * buffer objects may be assigned into a container that supports the
+ * MutableBufferSequence (for read) or ConstBufferSequence (for write) concepts:
+ *
+ * @code
+ * char d1[128];
+ * std::vector<char> d2(128);
+ * boost::array<char, 128> d3;
+ *
+ * boost::array<mutable_buffer, 3> bufs1 = {
+ * boost::asio::buffer(d1),
+ * boost::asio::buffer(d2),
+ * boost::asio::buffer(d3) };
+ * bytes_transferred = sock.receive(bufs1);
+ *
+ * std::vector<const_buffer> bufs2;
+ * bufs2.push_back(boost::asio::buffer(d1));
+ * bufs2.push_back(boost::asio::buffer(d2));
+ * bufs2.push_back(boost::asio::buffer(d3));
+ * bytes_transferred = sock.send(bufs2); @endcode

+/// Provides core I/O functionality.
+/**
+ * The io_service class provides the core I/O functionality for users of the
+ * asynchronous I/O objects, including:
+ *
+ * @li boost::asio::ip::tcp::socket
+ * @li boost::asio::ip::tcp::acceptor
+ * @li boost::asio::ip::udp::socket
+ * @li boost::asio::deadline_timer.
+ *
+ * The io_service class also includes facilities intended for developers of
+ * custom asynchronous services.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Safe, with the exception that calling reset()
+ * while there are unfinished run() calls results in undefined behaviour.
+ *
+ * @par Concepts:
+ * Dispatcher.
+ *
+ * @par Effect of exceptions thrown from handlers
+ *
+ * If an exception is thrown from a handler, the exception is allowed to
+ * propagate through the throwing thread's invocation of
+ * boost::asio::io_service::run(), boost::asio::io_service::run_one(),
+ * boost::asio::io_service::poll() or boost::asio::io_service::poll_one().
+ * No other threads that are calling any of these functions are affected. It is
+ * then the responsibility of the application to catch the exception.
+ *
+ * After the exception has been caught, the
+ * boost::asio::io_service::run(), boost::asio::io_service::run_one(),
+ * boost::asio::io_service::poll() or boost::asio::io_service::poll_one()
+ * call may be restarted @em without the need for an intervening call to
+ * boost::asio::io_service::reset(). This allows the thread to rejoin the
+ * io_service's thread pool without impacting any other threads in the pool.
+ *
+ * For example:
+ *
+ * @code
+ * boost::asio::io_service io_service;
+ * ...
+ * for (;;)
+ * {
+ * try
+ * {
+ * io_service.run();
+ * break; // run() exited normally
+ * }
+ * catch (my_exception& e)
+ * {
+ * // Deal with exception as appropriate.
+ * }

+ * @par Stopping the io_service from running out of work
+ *
+ * Some applications may need to prevent an io_service's run() call from
+ * returning when there is no more work to do. For example, the io_service may
+ * be being run in a background thread that is launched prior to the
+ * application's asynchronous operations. The run() call may be kept running by
+ * creating an object of type boost::asio::io_service::work:
+ *
+ * @code boost::asio::io_service io_service;
+ * boost::asio::io_service::work work(io_service);
+ * ... @endcode
+ *
+ * To effect a shutdown, the application will then need to call the io_service's
+ * stop() member function. This will cause the io_service run() call to return
+ * as soon as possible, abandoning unfinished operations and without permitting
+ * ready handlers to be dispatched.
+ *
+ * Alternatively, if the application requires that all operations and handlers
+ * be allowed to finish normally, the work object may be explicitly destroyed.
+ *
+ * @code boost::asio::io_service io_service;
+ * auto_ptr<boost::asio::io_service::work> work(
+ * new boost::asio::io_service::work(io_service));
+ * ...
+ * work.reset(); // Allow run() to exit. @endcode

+ * indicates a match, the operation completes immediately.
+ *
+ * @param s The stream from which the data is to be read. The type must support
+ * the AsyncReadStream concept.
+ *
+ * @param b A streambuf object into which the data will be read.
+ *
+ * @param match_condition The function object to be called to determine whether
+ * a match exists. The signature of the function object must be:
+ * @code pair<iterator, bool> match_condition(iterator begin, iterator end);
+ * @endcode
+ * where @c iterator represents the type:
+ * @code buffers_iterator<basic_streambuf<Allocator>::const_buffers_type>
+ * @endcode
+ * The iterator parameters @c begin and @c end define the range of bytes to be
+ * scanned to determine whether there is a match. The @c first member of the
+ * return value is an iterator marking one-past-the-end of the bytes that have
+ * been consumed by the match function. This iterator is used to calculate the
+ * @c begin parameter for any subsequent invocation of the match condition. The
+ * @c second member of the return value is true if a match has been found, false
+ * otherwise.
+ *
+ * @param handler The handler to be called when the read operation completes.
+ * Copies will be made of the handler as required. The function signature of the
+ * handler must be:
+ * @code void handler(
+ * // Result of operation.
+ * const boost::system::error_code& error,
+ *
+ * // The number of bytes in the streambuf's get
+ * // area that have been fully consumed by the
+ * // match function. O if an error occurred.
+ * std::size_t bytes_transferred
+ * ); @endcode
+ * Regardless of whether the asynchronous operation completes immediately or
+ * not, the handler will not be invoked from within this function. Invocation of
+ * the handler will be performed in a manner equivalent to using
+ * boost::asio::io_service::post().
+ *
+ * @note After a successful async_read_until operation, the streambuf may
+ * contain additional data beyond that which matched the function object. An
+ * application will typically leave that data in the streambuf for a subsequent
+ * async_read_until operation to examine.
+ *
+ * @note The default implementation of the @c is_match_condition type trait
+ * evaluates to true for function pointers and function objects with a
+ * @c result_type typedef. It must be specialised for other user-defined
+ * function objects.
+ *
+ * @par Examples
+ * To asynchronously read data into a streambuf until whitespace is encountered:
+ * @code typedef boost::asio::buffers_iterator<
+ * boost::asio::streambuf::const_buffers_type> iterator;
+ *
+ * std::pair<iterator, bool>
+ * match_whitespace(iterator begin, iterator end)
+ * {
+ * iterator i = begin;
+ * while (i != end)
+ * if (std::isspace(*i++))
+ * return std::make_pair(i, true);
+ * return std::make_pair(i, false);
+ * }
+ * ...
+ * void handler(const boost::system::error_code& e, std::size_t size);
+ * ...
+ * boost::asio::streambuf b;
+ * boost::asio::async_read_until(s, b, match_whitespace, handler);
+ * @endcode
+ *
+ * To asynchronously read data into a streambuf until a matching character is
+ * found:
+ * @code class match_char
+ * {
+ * public:
+ * explicit match_char(char c) : c_(c) {}
+ *
+ * template <typename Iterator>
+ * std::pair<Iterator, bool> operator()(
+ * Iterator begin, Iterator end) const
+ * {
+ * Iterator i = begin;
+ * while (i != end)
+ * if (c_ == *i++)
+ * return std::make_pair(i, true);
+ * return std::make_pair(i, false);
+ * }
+ *
+ * private:
+ * char c_;
+ * };
+ *
+ * namespace asio {
+ * template <> struct is_match_condition<match_char>

+ * This operation is implemented in terms of zero or more calls to the device's
+ * async_write_some_at function.
+ *
+ * @param d The device to which the data is to be written. The type must support
+ * the AsyncRandomAccessWriteDevice concept.
+ *
+ * @param offset The offset at which the data will be written.
+ *
+ * @param buffers One or more buffers containing the data to be written.
+ * Although the buffers object may be copied as necessary, ownership of the
+ * underlying memory blocks is retained by the caller, which must guarantee
+ * that they remain valid until the handler is called.
+ *
+ * @param completion_condition The function object to be called to determine
+ * whether the write operation is complete. The signature of the function object
+ * must be:
+ * @code std::size_t completion_condition(
+ * // Result of latest async_write_some_at operation.
+ * const boost::system::error_code& error,
+ *
+ * // Number of bytes transferred so far.
+ * std::size_t bytes_transferred
+ * ); @endcode
+ * A return value of 0 indicates that the write operation is complete. A
+ * non-zero return value indicates the maximum number of bytes to be written on
+ * the next call to the device's async_write_some_at function.
+ *
+ * @param handler The handler to be called when the write operation completes.
+ * Copies will be made of the handler as required. The function signature of the
+ * handler must be:
+ * @code void handler(
+ * // Result of operation.
+ * const boost::system::error_code& error,
+ *
+ * // Number of bytes written from the buffers. If an error
+ * // occurred, this will be less than the sum of the buffer sizes.
+ * std::size_t bytes_transferred
+ * ); @endcode
+ * Regardless of whether the asynchronous operation completes immediately or
+ * not, the handler will not be invoked from within this function. Invocation of
+ * the handler will be performed in a manner equivalent to using
+ * boost::asio::io_service::post().
+ *
+ * @par Example
+ * To write a single data buffer use the @ref buffer function as follows:
+ * @code boost::asio::async_write_at(d, 42,
+ * boost::asio::buffer(data, size),
+ * boost::asio::transfer_at_least(32),
+ * handler); @endcode
+ * See the @ref buffer documentation for information on writing multiple
+ * buffers in one go, and how to use it with arrays, boost::array or
+ * std::vector.
