+ * \brief Load the audio data of a WAVE file into memory
+ *
+ * Loading a WAVE file requires \c src, \c spec, \c audio_buf and \c audio_len
+ * to be valid pointers. The entire data portion of the file is then loaded
+ * into memory and decoded if necessary.
+ *
+ * If \c freesrc is non-zero, the data source gets automatically closed and
+ * freed before the function returns.
+ *
+ * Supported are RIFF WAVE files with the formats PCM (8, 16, 24, and 32 bits),
+ * IEEE Float (32 bits), Microsoft ADPCM and IMA ADPCM (4 bits), and A-law and
+ * µ-law (8 bits). Other formats are currently unsupported and cause an error.
+ *
+ * If this function succeeds, the pointer returned by it is equal to \c spec
+ * and the pointer to the audio data allocated by the function is written to
+ * \c audio_buf and its length in bytes to \c audio_len. The \ref SDL_AudioSpec
+ * members \c freq, \c channels, and \c format are set to the values of the
+ * audio data in the buffer. The \c samples member is set to a sane default and
+ * all others are set to zero.
+ *
+ * It's necessary to use SDL_FreeWAV() to free the audio data returned in
+ * \c audio_buf when it is no longer used.
+ *
+ * Because of the underspecification of the Waveform format, there are many
+ * problematic files in the wild that cause issues with strict decoders. To
+ * provide compatibility with these files, this decoder is lenient in regards
+ * to the truncation of the file, the fact chunk, and the size of the RIFF
+ * chunk. The hints SDL_HINT_WAVE_RIFF_CHUNK_SIZE, SDL_HINT_WAVE_TRUNCATION,
+ * and SDL_HINT_WAVE_FACT_CHUNK can be used to tune the behavior of the
+ * loading process.
+ *
+ * Any file that is invalid (due to truncation, corruption, or wrong values in
+ * the headers), too big, or unsupported causes an error. Additionally, any
+ * critical I/O error from the data source will terminate the loading process
+ * with an error. The function returns NULL on error and in all cases (with the
+ * exception of \c src being NULL), an appropriate error message will be set.
+ *

+ * \file SDL_haptic.h
+ *
+ * \brief The SDL haptic subsystem allows you to control haptic (force feedback)
+ * devices.
+ *
+ * The basic usage is as follows:
+ * - Initialize the subsystem (::SDL_INIT_HAPTIC).
+ * - Open a haptic device.
+ * - SDL_HapticOpen() to open from index.
+ * - SDL_HapticOpenFromJoystick() to open from an existing joystick.
+ * - Create an effect (::SDL_HapticEffect).
+ * - Upload the effect with SDL_HapticNewEffect().
+ * - Run the effect with SDL_HapticRunEffect().
+ * - (optional) Free the effect with SDL_HapticDestroyEffect().
+ * - Close the haptic device with SDL_HapticClose().
+ *
+ * \par Simple rumble example:
+ * \code
+ * SDL_Haptic *haptic;
+ *
+ * // Open the device
+ * haptic = SDL_HapticOpen( 0 );
+ * if (haptic == NULL)
+ * return -1;
+ *
+ * // Initialize simple rumble
+ * if (SDL_HapticRumbleInit( haptic ) != 0)
+ * return -1;
+ *
+ * // Play effect at 50% strength for 2 seconds
+ * if (SDL_HapticRumblePlay( haptic, 0.5, 2000 ) != 0)
+ * return -1;
+ * SDL_Delay( 2000 );
+ *
+ * // Clean up
+ * SDL_HapticClose( haptic );
+ * \endcode
+ *
+ * \par Complete example:
+ * \code
+ * int test_haptic( SDL_Joystick * joystick ) {
+ * SDL_Haptic *haptic;
+ * SDL_HapticEffect effect;
+ * int effect_id;
+ *
+ * // Open the device
+ * haptic = SDL_HapticOpenFromJoystick( joystick );
+ * if (haptic == NULL) return -1; // Most likely joystick isn't haptic
+ *
+ * // See if it can do sine waves
+ * if ((SDL_HapticQuery(haptic) & SDL_HAPTIC_SINE)==0) {
+ * SDL_HapticClose(haptic); // No sine effect
+ * return -1;
+ * }
+ *
+ * // Create the effect
+ * memset( &effect, 0, sizeof(SDL_HapticEffect) ); // 0 is safe default
+ * effect.type = SDL_HAPTIC_SINE;
+ * effect.periodic.direction.type = SDL_HAPTIC_POLAR; // Polar coordinates
+ * effect.periodic.direction.dir[0] = 18000; // Force comes from south
+ * effect.periodic.period = 1000; // 1000 ms
+ * effect.periodic.magnitude = 20000; // 20000/32767 strength
+ * effect.periodic.length = 5000; // 5 seconds long
+ * effect.periodic.attack_length = 1000; // Takes 1 second to get max strength
+ * effect.periodic.fade_length = 1000; // Takes 1 second to fade away
+ *
+ * // Upload the effect
+ * effect_id = SDL_HapticNewEffect( haptic, &effect );
+ *
+ * // Test the effect
+ * SDL_HapticRunEffect( haptic, effect_id, 1 );
+ * SDL_Delay( 5000); // Wait for the effect to finish
+ *
+ * // We destroy the effect, although closing the device also does this
+ * SDL_HapticDestroyEffect( haptic, effect_id );
+ *
+ * // Close the device
+ * SDL_HapticClose(haptic);
+ *
+ * return 0; // Success
+ * }
+ * \endcode

+ *
+ * If type is ::SDL_HAPTIC_POLAR, direction is encoded by hundredths of a
+ * degree starting north and turning clockwise. ::SDL_HAPTIC_POLAR only uses
+ * the first \c dir parameter. The cardinal directions would be:
+ * - North: 0 (0 degrees)
+ * - East: 9000 (90 degrees)
+ * - South: 18000 (180 degrees)
+ * - West: 27000 (270 degrees)
+ *
+ * If type is ::SDL_HAPTIC_CARTESIAN, direction is encoded by three positions
+ * (X axis, Y axis and Z axis (with 3 axes)). ::SDL_HAPTIC_CARTESIAN uses
+ * the first three \c dir parameters. The cardinal directions would be:
+ * - North: 0,-1, 0
+ * - East: 1, 0, 0
+ * - South: 0, 1, 0
+ * - West: -1, 0, 0
+ *
+ * The Z axis represents the height of the effect if supported, otherwise
+ * it's unused. In cartesian encoding (1, 2) would be the same as (2, 4), you
+ * can use any multiple you want, only the direction matters.
+ *
+ * If type is ::SDL_HAPTIC_SPHERICAL, direction is encoded by two rotations.
+ * The first two \c dir parameters are used. The \c dir parameters are as
+ * follows (all values are in hundredths of degrees):
+ * - Degrees from (1, 0) rotated towards (0, 1).
+ * - Degrees towards (0, 0, 1) (device needs at least 3 axes).

+/** \brief Allows back-button-press events on Windows Phone to be marked as handled
+ *
+ * Windows Phone devices typically feature a Back button. When pressed,
+ * the OS will emit back-button-press events, which apps are expected to
+ * handle in an appropriate manner. If apps do not explicitly mark these
+ * events as 'Handled', then the OS will invoke its default behavior for
+ * unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
+ * terminate the app (and attempt to switch to the previous app, or to the
+ * device's home screen).
+ *
+ * Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
+ * to mark back-button-press events as Handled, if and when one is sent to
+ * the app.
+ *
+ * Internally, Windows Phone sends back button events as parameters to
+ * special back-button-press callback functions. Apps that need to respond
+ * to back-button-press events are expected to register one or more
+ * callback functions for such, shortly after being launched (during the
+ * app's initialization phase). After the back button is pressed, the OS
+ * will invoke these callbacks. If the app's callback(s) do not explicitly
+ * mark the event as handled by the time they return, or if the app never
+ * registers one of these callback, the OS will consider the event
+ * un-handled, and it will apply its default back button behavior (terminate
+ * the app).
+ *
+ * SDL registers its own back-button-press callback with the Windows Phone
+ * OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
+ * and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
+ * it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
+ * If the hint's value is set to "1", the back button event's Handled
+ * property will get set to 'true'. If the hint's value is set to something
+ * else, or if it is unset, SDL will leave the event's Handled property
+ * alone. (By default, the OS sets this property to 'false', to note.)
+ *
+ * SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
+ * back button is pressed, or can set it in direct-response to a back button
+ * being pressed.
+ *
+ * In order to get notified when a back button is pressed, SDL apps should
+ * register a callback function with SDL_AddEventWatch(), and have it listen
+ * for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK.
+ * (Alternatively, SDL_KEYUP events can be listened-for. Listening for
+ * either event type is suitable.) Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON
+ * set by such a callback, will be applied to the OS' current
+ * back-button-press event.
+ *
+ * More details on back button behavior in Windows Phone apps can be found
+ * at the following page, on Microsoft's developer site:
+ * http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj247550(v=vs.105).aspx
