/// 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.
*
* A deadline timer is always in one of two states: "expired" or "not expired".
* If the wait() or async_wait() function is called on an expired timer, the
* wait operation will complete immediately.
*
* Most applications will use the 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.
* 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 asio::error_code& error)
* {
* if (!error)
* {
* // Timer expired.
* }
* }
*
* ...
*
* // Construct a timer with an absolute expiry time.
* 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 asio::error_code& e)
* {
* if (e != asio::error::operation_aborted)
* {
* // Timer was not cancelled, take necessary action.
* }
* }
* @endcode
*
* @li The 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 asio::error_code passed to
* it contains the value asio::error::operation_aborted.

/**
* The basic_signal_set class template provides the ability to perform an
* asynchronous wait for one or more signals to occur.
*
* Most applications will use the asio::signal_set typedef.
*
* @par Thread Safety
* @e Distinct @e objects: Safe.@n
* @e Shared @e objects: Unsafe.
*
* @par Example
* Performing an asynchronous wait:
* @code
* void handler(
* const asio::error_code& error,
* int signal_number)
* {
* if (!error)
* {
* // A signal occurred.
* }
* }
*
* ...
*
* // Construct a signal set registered for process termination.
* asio::signal_set signals(io_service, SIGINT, SIGTERM);
*
* // Start an asynchronous wait for one of the signals to occur.
* signals.async_wait(handler);
* @endcode
*
* @par Queueing of signal notifications
*
* If a signal is registered with a signal_set, and the signal occurs when
* there are no waiting handlers, then the signal notification is queued. The
* next async_wait operation on that signal_set will dequeue the notification.
* If multiple notifications are queued, subsequent async_wait operations
* dequeue them one at a time. Signal notifications are dequeued in order of
* ascending signal number.
*
* If a signal number is removed from a signal_set (using the @c remove or @c
* erase member functions) then any queued notifications for that signal are
* discarded.
*
* @par Multiple registration of signals
*
* The same signal number may be registered with different signal_set objects.
* When the signal occurs, one handler is called for each signal_set object.
*
* Note that multiple registration only works for signals that are registered
* using Asio. The application must not also register a signal handler using
* functions such as @c signal() or @c sigaction().
*
* @par Signal masking on POSIX platforms
*
* POSIX allows signals to be blocked using functions such as @c sigprocmask()
* and @c pthread_sigmask(). For signals to be delivered, programs must ensure
* that any signals registered using signal_set objects are unblocked in at
* least one thread.

/// 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
* 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
* asio::streambuf b;
*
* // reserve 512 bytes in output sequence
* asio::streambuf::mutable_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;
* @endcode

/// Provides waitable timer functionality.
/**
* The basic_waitable_timer class template provides the ability to perform a
* blocking or asynchronous wait for a timer to expire.
*
* A waitable timer is always in one of two states: "expired" or "not expired".
* If the wait() or async_wait() function is called on an expired timer, the
* wait operation will complete immediately.
*
* Most applications will use one of the asio::steady_timer,
* asio::system_timer or asio::high_resolution_timer typedefs.
*
* @note This waitable timer functionality is for use with the C++11 standard
* library's @c &lt;chrono&gt; facility, or with the Boost.Chrono library.
*
* @par Thread Safety
* @e Distinct @e objects: Safe.@n
* @e Shared @e objects: Unsafe.
*
* @par Examples
* Performing a blocking wait (C++11):
* @code
* // Construct a timer without setting an expiry time.
* asio::steady_timer timer(io_service);
*
* // Set an expiry time relative to now.
* timer.expires_from_now(std::chrono::seconds(5));
*
* // Wait for the timer to expire.
* timer.wait();
* @endcode
*
* @par
* Performing an asynchronous wait (C++11):
* @code
* void handler(const asio::error_code& error)
* {
* if (!error)
* {
* // Timer expired.
* }
* }
*
* ...
*
* // Construct a timer with an absolute expiry time.
* asio::steady_timer timer(io_service,
* std::chrono::steady_clock::now() + std::chrono::seconds(60));
*
* // Start an asynchronous wait.
* timer.async_wait(handler);
* @endcode
*
* @par Changing an active waitable 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 asio::error_code& e)
* {
* if (e != asio::error::operation_aborted)
* {
* // Timer was not cancelled, take necessary action.
* }
* }
* @endcode
*
* @li The asio::basic_waitable_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 asio::error_code passed to
* it contains the value asio::error::operation_aborted.

namespace asio {
namespace detail {
class coroutine_ref;
} // namespace detail
/// Provides support for implementing stackless coroutines.
/**
* The @c coroutine class may be used to implement stackless coroutines. The
* class itself is used to store the current state of the coroutine.
*
* Coroutines are copy-constructible and assignable, and the space overhead is
* a single int. They can be used as a base class:
*
* @code class session : coroutine
* {
* ...
* }; @endcode
*
* or as a data member:
*
* @code class session
* {
* ...
* coroutine coro_;
* }; @endcode
*
* or even bound in as a function argument using lambdas or @c bind(). The
* important thing is that as the application maintains a copy of the object
* for as long as the coroutine must be kept alive.
*
* @par Pseudo-keywords
*
* A coroutine is used in conjunction with certain "pseudo-keywords", which
* are implemented as macros. These macros are defined by a header file:
*
* @code #include <asio/yield.hpp>@endcode
*
* and may conversely be undefined as follows:
*
* @code #include <asio/unyield.hpp>@endcode
*
* <b>reenter</b>
*
* The @c reenter macro is used to define the body of a coroutine. It takes a
* single argument: a pointer or reference to a coroutine object. For example,
* if the base class is a coroutine object you may write:
*
* @code reenter (this)
* {
* ... coroutine body ...
* } @endcode
*
* and if a data member or other variable you can write:
*
* @code reenter (coro_)
* {
* ... coroutine body ...
* } @endcode
*
* When @c reenter is executed at runtime, control jumps to the location of the
* last @c yield or @c fork.
*
* The coroutine body may also be a single statement, such as:
*
* @code reenter (this) for (;;)
* {
* ...
* } @endcode
*
* @b Limitation: The @c reenter macro is implemented using a switch. This
* means that you must take care when using local variables within the
* coroutine body. The local variable is not allowed in a position where
* reentering the coroutine could bypass the variable definition.
*
* <b>yield <em>statement</em></b>
*
* This form of the @c yield keyword is often used with asynchronous operations:
*
* @code yield socket_->async_read_some(buffer(*buffer_), *this); @endcode
*
* This divides into four logical steps:
*
* @li @c yield saves the current state of the coroutine.
* @li The statement initiates the asynchronous operation.
* @li The resume point is defined immediately following the statement.
* @li Control is transferred to the end of the coroutine body.
*
* When the asynchronous operation completes, the function object is invoked
* and @c reenter causes control to transfer to the resume point. It is
* important to remember to carry the coroutine state forward with the
* asynchronous operation. In the above snippet, the current class is a
* function object object with a coroutine object as base class or data member.
*
* The statement may also be a compound statement, and this permits us to
* define local variables with limited scope:
*
* @code yield
* {
* mutable_buffers_1 b = buffer(*buffer_);
* socket_->async_read_some(b, *this);
* } @endcode
*
* <b>yield return <em>expression</em> ;</b>
*
* This form of @c yield is often used in generators or coroutine-based parsers.
* For example, the function object:
*
* @code struct interleave : coroutine
* {
* istream& is1;
* istream& is2;
* char operator()(char c)
* {
* reenter (this) for (;;)
* {
* yield return is1.get();
* yield return is2.get();
* }
* }
* }; @endcode
*
* defines a trivial coroutine that interleaves the characters from two input
* streams.
*
* This type of @c yield divides into three logical steps:
*
* @li @c yield saves the current state of the coroutine.
* @li The resume point is defined immediately following the semicolon.
* @li The value of the expression is returned from the function.
*
* <b>yield ;</b>
*
* This form of @c yield is equivalent to the following steps:
*
* @li @c yield saves the current state of the coroutine.
* @li The resume point is defined immediately following the semicolon.
* @li Control is transferred to the end of the coroutine body.
*
* This form might be applied when coroutines are used for cooperative
* threading and scheduling is explicitly managed. For example:
*
* @code struct task : coroutine
* {
* ...
* void operator()()
* {
* reenter (this)
* {
* while (... not finished ...)
* {
* ... do something ...
* yield;
* ... do some more ...
* yield;
* }
* }
* }
* ...
* };
* ...
* task t1, t2;
* for (;;)
* {
* t1();
* t2();
* } @endcode
*
* <b>yield break ;</b>
*
* The final form of @c yield is used to explicitly terminate the coroutine.
* This form is comprised of two steps:
*
* @li @c yield sets the coroutine state to indicate termination.
* @li Control is transferred to the end of the coroutine body.
*
* Once terminated, calls to is_complete() return true and the coroutine cannot
* be reentered.
*
* Note that a coroutine may also be implicitly terminated if the coroutine
* body is exited without a yield, e.g. by return, throw or by running to the
* end of the body.
*
* <b>fork <em>statement</em></b>
*
* The @c fork pseudo-keyword is used when "forking" a coroutine, i.e. splitting
* it into two (or more) copies. One use of @c fork is in a server, where a new
* coroutine is created to handle each client connection:
*
* @code reenter (this)
* {
* do
* {
* socket_.reset(new tcp::socket(io_service_));
* yield acceptor->async_accept(*socket_, *this);
* fork server(*this)();
* } while (is_parent());
* ... client-specific handling follows ...
* } @endcode
*
* The logical steps involved in a @c fork are:
*
* @li @c fork saves the current state of the coroutine.
* @li The statement creates a copy of the coroutine and either executes it
* immediately or schedules it for later execution.
* @li The resume point is defined immediately following the semicolon.
* @li For the "parent", control immediately continues from the next line.
*
* The functions is_parent() and is_child() can be used to differentiate
* between parent and child. You would use these functions to alter subsequent
* control flow.
*
* Note that @c fork doesn't do the actual forking by itself. It is the
* application's responsibility to create a clone of the coroutine and call it.
* The clone can be called immediately, as above, or scheduled for delayed
* execution using something like io_service::post().
*
* @par Alternate macro names
*
* If preferred, an application can use macro names that follow a more typical
* naming convention, rather than the pseudo-keywords. These are:
*
* @li @c ASIO_CORO_REENTER instead of @c reenter
* @li @c ASIO_CORO_YIELD instead of @c yield
* @li @c ASIO_CORO_FORK instead of @c fork
