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

///
/// For maximum robustness, sf::Lock should always be used
/// to lock/unlock a mutex.
///

/// \code
/// sf::Mutex mutex;
///
/// void function()
/// {
/// sf::Lock lock(mutex); // mutex is now locked
///
/// 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
/// part of the code.
///
/// \code
/// sf::Mutex mutex;
///
/// void function()
/// {
/// {
/// sf::Lock lock(mutex);
/// codeThatRequiresProtection();
///
/// } // mutex is unlocked here
///
/// codeThatDoesntCareAboutTheMutex();
/// }
/// \endcode

/// Having a mutex locked longer than required is a bad practice

/// a mutex is locked, other threads may be waiting doing nothing
/// until it is released.

/// Mutex stands for "MUTual EXclusion". A mutex is a
/// synchronization object, used when multiple threads are involved.
///
/// When you want to protect a part of the code from being accessed
/// simultaneously by multiple threads, you typically use a
/// mutex. When a thread is locked by a mutex, any other thread
/// trying to lock it will be blocked until the mutex is released
/// by the thread that locked it. This way, you can allow only
/// one thread at a time to access a critical region of your code.
///
/// Usage example:
/// \code
/// Database database; // this is a critical resource that needs some protection
/// sf::Mutex mutex;
///
/// void thread1()
/// {
/// mutex.lock(); // this call will block the thread if the mutex is already locked by thread2
/// database.write(...);
/// mutex.unlock(); // if thread2 was waiting, it will now be unblocked
/// }
///
/// void thread2()
/// {
/// mutex.lock(); // this call will block the thread if the mutex is already locked by thread1
/// database.write(...);
/// mutex.unlock(); // if thread1 was waiting, it will now be unblocked
/// }
/// \endcode
///
/// Be very careful with mutexes. A bad usage can lead to bad problems,
/// like deadlocks (two threads are waiting for each other and the
/// application is globally stuck).
///
/// To make the usage of mutexes more robust, particularly in
/// environments where exceptions can be thrown, you should
/// use the helper class sf::Lock to lock/unlock mutexes.
///
/// SFML mutexes are recursive, which means that you can lock
/// a mutex multiple times in the same thread without creating
/// a deadlock. In this case, the first call to lock() behaves
/// as usual, and the following ones have no effect.
/// However, you must call unlock() exactly as many times as you
/// called lock(). If you don't, the mutex won't be released.

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

///
/// To use a sf::Thread, you construct it directly with the

/// sf::Thread has multiple template constructors, which means
/// that you can use several types of entry points:

/// \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

/// 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())

/// void threadFunc(int argument)
/// {

/// }
///
