/// sf::Lock is a RAII wrapper for sf::Mutex. By unlocking

///
/// For maximum robustness, sf::Lock should always be used

///
/// functionThatMayThrowAnException(); // mutex is unlocked if this function throws
///
/// if (someCondition)
/// return; // mutex is unlocked
///
/// } // mutex is unlocked
/// \endcode
///
/// Because the mutex is not explicitly unlocked in the code,
/// it may remain locked longer than needed. If the region
/// of the code that needs to be protected by the mutex is
/// not the entire function, a good practice is to create a
/// smaller, inner scope so that the lock is limited to this

/// a mutex is locked, other threads may be waiting doing nothing

/// \ingroup system
///
/// Threads provide a way to run multiple parts of the code

/// is split and both the new thread and the caller run
/// in parallel.
///
/// To use a sf::Thread, you construct it directly with the
/// function to execute as the entry point of the thread.
/// sf::Thread has multiple template constructors, which means
/// that you can use several types of entry points:
/// \li non-member functions with no argument
/// \li non-member functions with one argument of any type
/// \li functors with no argument (this one is particularly useful for compatibility with boost/std::%bind)
/// \li functors with one argument of any type
/// \li member functions from any class with no argument
///
/// The function argument, if any, is copied in the sf::Thread
/// instance, as well as the functor (if the corresponding
/// constructor is used). Class instances, however, are passed
/// by pointer so you must make sure that the object won't be
/// destroyed while the thread is still using it.
///
/// The thread ends when its function is terminated. If the
/// owner sf::Thread instance is destroyed before the
/// thread is finished, the destructor will wait (see wait())
///
/// Usage examples:
/// \code
/// // example 1: non member function with one argument
///
/// void threadFunc(int argument)
/// {
/// ...
/// }
///
/// sf::Thread thread(&threadFunc, 5);
/// thread.launch(); // start the thread (internally calls threadFunc(5))
/// \endcode
///
/// \code
/// // example 2: member function
///
/// class Task
/// {
/// public:
/// void run()
/// {
/// ...
/// }
/// };
///
/// Task task;
/// sf::Thread thread(&Task::run, &task);
/// thread.launch(); // start the thread (internally calls task.run())
/// \endcode
///
/// \code
/// // example 3: functor
///
/// struct Task
/// {
/// void operator()()
/// {
/// ...
/// }
/// };
///
/// sf::Thread thread(Task());
/// thread.launch(); // start the thread (internally calls operator() on the Task instance)
/// \endcode
///
/// Creating parallel threads of execution can be dangerous:
/// all threads inside the same process share the same memory space,
/// which means that you may end up accessing the same variable
/// from multiple threads at the same time. To prevent this
/// kind of situations, you can use mutexes (see sf::Mutex).

/// sf::Time encapsulates a time value in a flexible way.
/// It allows to define a time value either as a number of
/// seconds, milliseconds or microseconds. It also works the
/// other way round: you can read a time value as either
/// a number of seconds, milliseconds or microseconds.
///
/// By using such a flexible interface, the API doesn't
/// impose any fixed type or resolution for time values,
/// and let the user choose its own favorite representation.
///
/// Time values support the usual mathematical operations:
/// you can add or subtract two times, multiply or divide
/// a time by a number, compare two times, etc.
///
/// Since they represent a time span and not an absolute time
/// value, times can also be negative.
///
/// Usage example:
/// \code
/// sf::Time t1 = sf::seconds(0.1f);
/// Int32 milli = t1.asMilliseconds(); // 100
///
/// sf::Time t2 = sf::milliseconds(30);
/// Int64 micro = t2.asMicroseconds(); // 30000
///
/// sf::Time t3 = sf::microseconds(-800000);
/// float sec = t3.asSeconds(); // -0.8
/// \endcode
///
/// \code
/// void update(sf::Time elapsed)
/// {
/// position += speed * elapsed.asSeconds();
/// }
///
/// update(sf::milliseconds(100));
