* becomes the owner of the original "default" DosQObject. Furthermore if the binding language is garbage collected you
* should disable (pin/ref) the original object and unref in the DeleteDObject() callback. Since the wrapper has been created
* from QML is QML that expect to free the memory for it thus it shouldn't be destroyed by the QObject in the binded language.

# The QObject in the Nim language should not destroy its inner DosQObject

*
* ### REQUIRED: Buffer Padding
*
* The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what
* those bytes are initialized to, as long as they are allocated. These bytes will be read: if you
* using a sanitizer that verifies that no uninitialized byte is read, then you should initialize the
* SIMDJSON_PADDING bytes to avoid runtime warnings.
*
* If realloc_if_needed is true (the default), it is assumed that the buffer does *not* have enough padding,
* and it is copied into an enlarged temporary buffer before parsing. Thus the following is safe:
*
* const char *json = R"({"key":"value"})";
* const size_t json_len = std::strlen(json);
* simdjson::dom::parser parser;
* simdjson::dom::element element = parser.parse(json, json_len);
*
* If you set realloc_if_needed to false (e.g., parser.parse(json, json_len, false)),
* you must provide a buffer with at least SIMDJSON_PADDING extra bytes at the end.
* The benefit of setting realloc_if_needed to false is that you avoid a temporary
* memory allocation and a copy.
*
* The padded bytes may be read. It is not important how you initialize
* these bytes though we recommend a sensible default like null character values or spaces.
* For example, the following low-level code is safe:
*
* const char *json = R"({"key":"value"})";
* const size_t json_len = std::strlen(json);
* std::unique_ptr<char[]> padded_json_copy{new char[json_len + SIMDJSON_PADDING]};
* std::memcpy(padded_json_copy.get(), json, json_len);
* std::memset(padded_json_copy.get() + json_len, '\0', SIMDJSON_PADDING);
* simdjson::dom::parser parser;
* simdjson::dom::element element = parser.parse(padded_json_copy.get(), json_len, false);
*
* ### Parser Capacity
*
* If the parser's current capacity is less than len, it will allocate enough capacity
* to handle it (up to max_capacity).
*
* @param buf The JSON to parse. Must have at least len + SIMDJSON_PADDING allocated bytes, unless

* Parse a JSON document into a provide document instance and return a temporary reference to it.

* instance.
*
* dom::parser parser;

* element doc_root = parser.parse_into_document(doc, buf, len);
*
* The function eagerly parses the input: the input can be modified and discarded after
* the `parser.parse(buf, len)` call has completed.
*
* ### IMPORTANT: Document Lifetime
*
* After the call to parse_into_document, the parser is no longer needed.
*
* The JSON document lives in the document instance: you must keep the document
* instance alive while you navigate through it (i.e., used the returned value from
* parse_into_document). You are encourage to reuse the document instance
* many times with new data to avoid reallocations:
*
* dom::document doc;
* element doc_root1 = parser.parse_into_document(doc, buf1, len);
* //... doc_root1 is a pointer inside doc
* element doc_root2 = parser.parse_into_document(doc, buf1, len);
* //... doc_root2 is a pointer inside doc
* // at this point doc_root1 is no longer safe
*
* Moving the document instance is safe, but it invalidates the element instances. After
* moving a document, you can recover safe access to the document root with its `root()` method.
*
* @param doc The document instance where the parsed data will be stored (on success).
* @param buf The JSON to parse. Must have at least len + SIMDJSON_PADDING allocated bytes, unless
* realloc_if_needed is true.
* @param len The length of the JSON.
* @param realloc_if_needed Whether to reallocate and enlarge the JSON buffer to add padding.
* @return An element pointing at the root of document, or an error:
* - MEMALLOC if realloc_if_needed is true or the parser does not have enough capacity,
* and memory allocation fails.
* - CAPACITY if the parser does not have enough capacity and len > max_capacity.
* - other json errors if parsing fails. You should not rely on these errors to always the same for the
* same document: they may vary under runtime dispatch (so they may vary depending on your system and hardware).

*
* The file is loaded in memory and can be safely deleted after the `parser.load_many(path)`
* function has returned. The memory is held by the `parser` instance.
*
* The function is lazy: it may be that no more than one JSON document at a time is parsed.
* And, possibly, no document many have been parsed when the `parser.load_many(path)` function
* returned.
*
* ### Format
*
* The file must contain a series of one or more JSON documents, concatenated into a single
* buffer, separated by whitespace. It effectively parses until it has a fully valid document,
* then starts parsing the next document at that point. (It does this with more parallelism and
* lookahead than you might think, though.)
*
* Documents that consist of an object or array may omit the whitespace between them, concatenating
* with no separator. documents that consist of a single primitive (i.e. documents that are not
* arrays or objects) MUST be separated with whitespace.
*
* The documents must not exceed batch_size bytes (by default 1MB) or they will fail to parse.
* Setting batch_size to excessively large or excesively small values may impact negatively the
* performance.
*
* ### Error Handling
*
* All errors are returned during iteration: if there is a global error such as memory allocation,
* it will be yielded as the first result. Iteration always stops after the first error.
*
* As with all other simdjson methods, non-exception error handling is readily available through
* the same interface, requiring you to check the error before using the document:
*
* dom::parser parser;
* dom::document_stream docs;
* auto error = parser.load_many(path).get(docs);
* if (error) { cerr << error << endl; exit(1); }
* for (auto doc : docs) {
* std::string_view title;
* if ((error = doc["title"].get(title)) { cerr << error << endl; exit(1); }
* cout << title << endl;
* }
*
* ### Threads
*
* When compiled with SIMDJSON_THREADS_ENABLED, this method will use a single thread under the
* hood to do some lookahead.
*
* ### Parser Capacity
*
* If the parser's current capacity is less than batch_size, it will allocate enough capacity
* to handle it (up to max_capacity).
*
* @param path File name pointing at the concatenated JSON to parse.
* @param batch_size The batch size to use. MUST be larger than the largest document. The sweet
* spot is cache-related: small enough to fit in cache, yet big enough to
* parse as many documents as possible in one tight loop.
* Defaults to 1MB (as simdjson::dom::DEFAULT_BATCH_SIZE), which has been a reasonable sweet
* spot in our tests.
* If you set the batch_size to a value smaller than simdjson::dom::MINIMAL_BATCH_SIZE
* (currently 32B), it will be replaced by simdjson::dom::MINIMAL_BATCH_SIZE.
* @return The stream, or an error. An empty input will yield 0 documents rather than an EMPTY error. Errors:
* - IO_ERROR if there was an error opening or reading the file.
* - MEMALLOC if the parser does not have enough capacity and memory allocation fails.
* - CAPACITY if the parser does not have enough capacity and batch_size > max_capacity.
* - other json errors if parsing fails. You should not rely on these errors to always the same for the
* same document: they may vary under runtime dispatch (so they may vary depending on your system and hardware).

*
* ### REQUIRED: Buffer Padding
*
* The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what

/**
* Design notes:
* Instead of constructing a string_view and then comparing it with a
* user-provided strings, it is probably more performant to have dedicated
* functions taking as a parameter the string we want to compare against
* and return true when they are equal. That avoids the creation of a temporary
* std::string_view. Though it is possible for the compiler to avoid entirely
* any overhead due to string_view, relying too much on compiler magic is
* problematic: compiler magic sometimes fail, and then what do you do?
* Also, enticing users to rely on high-performance function is probably better
* on the long run.

*
* The buffer must have at least SIMDJSON_PADDING extra allocated bytes. It does not matter what
* those bytes are initialized to, as long as they are allocated. These bytes will be read: if you
* using a sanitizer that verifies that no uninitialized byte is read, then you should initialize the
* SIMDJSON_PADDING bytes to avoid runtime warnings.
*
* ### Threads
*
* When compiled with SIMDJSON_THREADS_ENABLED, this method will use a single thread under the
* hood to do some lookahead.
*
* ### Parser Capacity
*
* If the parser's current capacity is less than batch_size, it will allocate enough capacity
* to handle it (up to max_capacity).
*
* @param buf The concatenated JSON to parse.
* @param len The length of the concatenated JSON.
* @param batch_size The batch size to use. MUST be larger than the largest document. The sweet
* spot is cache-related: small enough to fit in cache, yet big enough to
* parse as many documents as possible in one tight loop.
* Defaults to 10MB, which has been a reasonable sweet spot in our tests.
* @return The stream, or an error. An empty input will yield 0 documents rather than an EMPTY error. Errors:
* - MEMALLOC if the parser does not have enough capacity and memory allocation fails
* - CAPACITY if the parser does not have enough capacity and batch_size > max_capacity.
* - other json errors if parsing fails. You should not rely on these errors to always the same for the
* same document: they may vary under runtime dispatch (so they may vary depending on your system and hardware).

// iterate over, we need to finish that iteration by skipping child values until we reach the
// Next state. In this state, depth > iter.depth, at_start == false, and error == SUCCESS.
//
// ## Error States
//
// In error states, we will yield exactly one more value before stopping. iter.depth == depth
// and at_start is always false. We decrement after yielding the error, moving to the Finished
// state.
//
// - Chained Error: When the object iterator is part of an error chain--for example, in
// `for (auto tweet : doc["tweets"])`, where the tweet field may be missing or not be an
// object--we yield that error in the loop, exactly once. In this state, error != SUCCESS and
// iter.depth == depth, and at_start == false. We decrement depth when we yield the error.
// - Missing Comma Error: When the iterator ++ method discovers there is no comma between fields,
// we flag that as an error and treat it exactly the same as a Chained Error. In this state,
// error == TAPE_ERROR, iter.depth == depth, and at_start == false.
//
// Errors that occur while reading a field to give to the user (such as when the key is not a
// string or the field is missing a colon) are yielded immediately. Depth is then decremented,
// moving to the Finished state without transitioning through an Error state at all.
//
// ## Terminal State

// The terminal state has iter.depth < depth. at_start is always false.

/**
* Whenever we move to another window, we need to update all pointers to make
* it appear as if the input buffer started at the beginning of the window.
*
* Take this input:
*
* {"z":5} {"1":1,"2":2,"4":4} [7, 10, 9] [15, 11, 12, 13] [154, 110, 112, 1311]
*
* Say you process the following window...
*
* '{"z":5} {"1":1,"2":2,"4":4} [7, 10, 9]'
*
* When you do so, the json_iterator has a pointer at the beginning of the memory region
* (pointing at the beginning of '{"z"...'.
*
* When you move to the window that starts at...
*
* '[7, 10, 9] [15, 11, 12, 13] ...
*
* then it is not sufficient to just run stage 1. You also need to re-anchor the
* json_iterator so that it believes we are starting at '[7, 10, 9]...'.
*
* Under the DOM front-end, this gets done automatically because the parser owns
* the pointer the data, and when you call stage1 and then stage2 on the same
* parser, then stage2 will run on the pointer acquired by stage1.
*
* That is, stage1 calls "this->buf = _buf" so the parser remembers the buffer that
* we used. But json_iterator has no callback when stage1 is called on the parser.
* In fact, I think that the parser is unaware of json_iterator.
*
*
* So we need to re-anchor the json_iterator after each call to stage 1 so that
* all of the pointers are in sync.

*
* rlgl v4.5 - A multi-OpenGL abstraction layer with an immediate-mode style API
*
* An abstraction layer for multiple OpenGL versions (1.1, 2.1, 3.3 Core, 4.3 Core, ES 2.0)
* that provides a pseudo-OpenGL 1.1 immediate-mode style API (rlVertex, rlTranslate, rlRotate...)
*
* When choosing an OpenGL backend different than OpenGL 1.1, some internal buffer are
* initialized on rlglInit() to accumulate vertex data.
*
* When an internal state change is required all the stored vertex data is renderer in batch,
* additionally, rlDrawRenderBatchActive() could be called to force flushing of the batch.
*
* Some additional resources are also loaded for convenience, here the complete list:
* - Default batch (RLGL.defaultBatch): RenderBatch system to accumulate vertex data
* - Default texture (RLGL.defaultTextureId): 1x1 white pixel R8G8B8A8
* - Default shader (RLGL.State.defaultShaderId, RLGL.State.defaultShaderLocs)
*
* Internal buffer (and additional resources) must be manually unloaded calling rlglClose().
*
*
* CONFIGURATION:
*
* #define GRAPHICS_API_OPENGL_11
* #define GRAPHICS_API_OPENGL_21
* #define GRAPHICS_API_OPENGL_33
* #define GRAPHICS_API_OPENGL_43
* #define GRAPHICS_API_OPENGL_ES2
* Use selected OpenGL graphics backend, should be supported by platform
* Those preprocessor defines are only used on rlgl module, if OpenGL version is
* required by any other module, use rlGetVersion() to check it
*
* #define RLGL_IMPLEMENTATION
* Generates the implementation of the library into the included file.
* If not defined, the library is in header only mode and can be included in other headers
* or source files without problems. But only ONE file should hold the implementation.
*
* #define RLGL_RENDER_TEXTURES_HINT
* Enable framebuffer objects (fbo) support (enabled by default)
* Some GPUs could not support them despite the OpenGL version
*
* #define RLGL_SHOW_GL_DETAILS_INFO
* Show OpenGL extensions and capabilities detailed logs on init
*
* #define RLGL_ENABLE_OPENGL_DEBUG_CONTEXT
* Enable debug context (only available on OpenGL 4.3)
*
* rlgl capabilities could be customized just defining some internal
* values before library inclusion (default values listed):
*
* #define RL_DEFAULT_BATCH_BUFFER_ELEMENTS 8192 // Default internal render batch elements limits
* #define RL_DEFAULT_BATCH_BUFFERS 1 // Default number of batch buffers (multi-buffering)
* #define RL_DEFAULT_BATCH_DRAWCALLS 256 // Default number of batch draw calls (by state changes: mode, texture)
* #define RL_DEFAULT_BATCH_MAX_TEXTURE_UNITS 4 // Maximum number of textures units that can be activated on batch drawing (SetShaderValueTexture())
*
* #define RL_MAX_MATRIX_STACK_SIZE 32 // Maximum size of internal Matrix stack
* #define RL_MAX_SHADER_LOCATIONS 32 // Maximum number of shader locations supported
* #define RL_CULL_DISTANCE_NEAR 0.01 // Default projection matrix near cull distance
* #define RL_CULL_DISTANCE_FAR 1000.0 // Default projection matrix far cull distance
*
* When loading a shader, the following vertex attribute and uniform
* location names are tried to be set automatically:
*
* #define RL_DEFAULT_SHADER_ATTRIB_NAME_POSITION "vertexPosition" // Bound by default to shader location: 0
* #define RL_DEFAULT_SHADER_ATTRIB_NAME_TEXCOORD "vertexTexCoord" // Bound by default to shader location: 1
* #define RL_DEFAULT_SHADER_ATTRIB_NAME_NORMAL "vertexNormal" // Bound by default to shader location: 2
* #define RL_DEFAULT_SHADER_ATTRIB_NAME_COLOR "vertexColor" // Bound by default to shader location: 3
* #define RL_DEFAULT_SHADER_ATTRIB_NAME_TANGENT "vertexTangent" // Bound by default to shader location: 4
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_MVP "mvp" // model-view-projection matrix
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_VIEW "matView" // view matrix
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_PROJECTION "matProjection" // projection matrix
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_MODEL "matModel" // model matrix
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_NORMAL "matNormal" // normal matrix (transpose(inverse(matModelView))
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_COLOR "colDiffuse" // color diffuse (base tint color, multiplied by texture color)
* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE0 "texture0" // texture0 (texture slot active 0)
* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE1 "texture1" // texture1 (texture slot active 1)
* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE2 "texture2" // texture2 (texture slot active 2)
*
* DEPENDENCIES:
*
* - OpenGL libraries (depending on platform and OpenGL version selected)
* - GLAD OpenGL extensions loading library (only for OpenGL 3.3 Core, 4.3 Core)

*
* raymath v1.5 - Math functions to work with Vector2, Vector3, Matrix and Quaternions
*
* CONFIGURATION:
*
* #define RAYMATH_IMPLEMENTATION
* Generates the implementation of the library into the included file.
* If not defined, the library is in header only mode and can be included in other headers
* or source files without problems. But only ONE file should hold the implementation.
*
* #define RAYMATH_STATIC_INLINE
* Define static inline functions code, so #include header suffices for use.
* This may use up lots of memory.
*
* CONVENTIONS:
*
* - Functions are always self-contained, no function use another raymath function inside,
* required code is directly re-implemented inside
* - Functions input parameters are always received by value (2 unavoidable exceptions)
* - Functions use always a "result" variable for return
* - Functions are always defined inline
* - Angles are always in radians (DEG2RAD/RAD2DEG macros provided for convenience)

*
* What happens when you open a URL varies wildly as well: your game window
* may lose focus (and may or may not lose focus if your game was fullscreen
* or grabbing input at the time). On mobile devices, your app will likely
* move to the background or your process might be paused. Any given platform
* may or may not handle a given URL.
*
* If this is unimplemented (or simply unavailable) for a platform, this will
* fail with an error. A successful result does not mean the URL loaded, just
* that we launched _something_ to handle it (or at least believe we did).
*
* All this to say: this function can be useful, but you should definitely
* test it on every platform you target.

/**
* \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
* SDL_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

\endverbatim
*
* 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).
*
*
* Example of force coming from the south with all encodings (force coming
* from the south means the user will have to pull the stick to counteract):
* \code
* SDL_HapticDirection direction;
*
* // Cartesian directions
* direction.type = SDL_HAPTIC_CARTESIAN; // Using cartesian direction encoding.
* direction.dir[0] = 0; // X position
* direction.dir[1] = 1; // Y position
* // Assuming the device has 2 axes, we don't need to specify third parameter.
*
* // Polar directions
* direction.type = SDL_HAPTIC_POLAR; // We'll be using polar direction encoding.
* direction.dir[0] = 18000; // Polar only uses first parameter
*
* // Spherical coordinates
* direction.type = SDL_HAPTIC_SPHERICAL; // Spherical encoding
* direction.dir[0] = 9000; // Since we only have two axes we don't need more parameters.

* All values max at 32767 (0x7FFF). Signed values also can be negative.
* Time values unless specified otherwise are in milliseconds.
*
* You can also pass ::SDL_HAPTIC_INFINITY to length instead of a 0-32767
* value. Neither delay, interval, attack_length nor fade_length support
* ::SDL_HAPTIC_INFINITY. Fade will also not be used since effect never ends.
*
* Additionally, the ::SDL_HAPTIC_RAMP effect does not support a duration of
* ::SDL_HAPTIC_INFINITY.
*
* Button triggers may not be supported on all devices, it is advised to not
* use them if possible. Buttons start at index 1 instead of index 0 like
* the joystick.
*
* If both attack_length and fade_level are 0, the envelope is not used,
* otherwise both values are used.
*
* Common parts:
* \code
* // Replay - All effects have this
* Uint32 length; // Duration of effect (ms).
* Uint16 delay; // Delay before starting effect.
*
* // Trigger - All effects have this
* Uint16 button; // Button that triggers effect.
* Uint16 interval; // How soon before effect can be triggered again.
*
* // Envelope - All effects except condition effects have this
* Uint16 attack_length; // Duration of the attack (ms).
* Uint16 attack_level; // Level at the start of the attack.
* Uint16 fade_length; // Duration of the fade out (ms).
* Uint16 fade_level; // Level at the end of the fade.
* \endcode
*

* Here we have an example of a constant effect evolution in time:

* Please note that SDL 2.0 before 2.0.5 did not support recording; as such,
* this function would fail if `iscapture` was not zero. Starting with SDL
* 2.0.5, recording is implemented and this value can be non-zero.
*
* Passing in a `device` name of NULL requests the most reasonable default
* (and is equivalent to what SDL_OpenAudio() does to choose a device). The
* `device` name is a UTF-8 string reported by SDL_GetAudioDeviceName(), but
* some drivers allow arbitrary and driver-specific strings, such as a
* hostname/IP address for a remote audio server, or a filename in the
* diskaudio driver.
*
* An opened audio device starts out paused, and should be enabled for playing
* by calling SDL_PauseAudioDevice(devid, 0) when you are ready for your audio
* callback function to be called. Since the audio driver may modify the
* requested size of the audio buffer, you should allocate any local mixing
* buffers after you open the audio device.
*
* The audio callback runs in a separate thread in most cases; you can prevent
* race conditions between your callback and other threads without fully
* pausing playback with SDL_LockAudioDevice(). For more information about the
* callback, see SDL_AudioSpec.
*
* Managing the audio spec via 'desired' and 'obtained':
*
* When filling in the desired audio spec structure:
*
* - `desired->freq` should be the frequency in sample-frames-per-second (Hz).
* - `desired->format` should be the audio format (`AUDIO_S16SYS`, etc).
* - `desired->samples` is the desired size of the audio buffer, in _sample
* frames_ (with stereo output, two samples--left and right--would make a
* single sample frame). This number should be a power of two, and may be
* adjusted by the audio driver to a value more suitable for the hardware.
* Good values seem to range between 512 and 8096 inclusive, depending on
* the application and CPU speed. Smaller values reduce latency, but can
* lead to underflow if the application is doing heavy processing and cannot
* fill the audio buffer in time. Note that the number of sample frames is
* directly related to time by the following formula: `ms =
* (sampleframes*1000)/freq`
* - `desired->size` is the size in _bytes_ of the audio buffer, and is
* calculated by SDL_OpenAudioDevice(). You don't initialize this.
* - `desired->silence` is the value used to set the buffer to silence, and is
* calculated by SDL_OpenAudioDevice(). You don't initialize this.
* - `desired->callback` should be set to a function that will be called when
* the audio device is ready for more data. It is passed a pointer to the
* audio buffer, and the length in bytes of the audio buffer. This function
* usually runs in a separate thread, and so you should protect data
* structures that it accesses by calling SDL_LockAudioDevice() and
* SDL_UnlockAudioDevice() in your code. Alternately, you may pass a NULL
* pointer here, and call SDL_QueueAudio() with some frequency, to queue
* more audio samples to be played (or for capture devices, call
* SDL_DequeueAudio() with some frequency, to obtain audio samples).
* - `desired->userdata` is passed as the first parameter to your callback
* function. If you passed a NULL callback, this value is ignored.
*
* `allowed_changes` can have the following flags OR'd together:
*
* - `SDL_AUDIO_ALLOW_FREQUENCY_CHANGE`
* - `SDL_AUDIO_ALLOW_FORMAT_CHANGE`
* - `SDL_AUDIO_ALLOW_CHANNELS_CHANGE`
* - `SDL_AUDIO_ALLOW_SAMPLES_CHANGE`
* - `SDL_AUDIO_ALLOW_ANY_CHANGE`
*
* These flags specify how SDL should behave when a device cannot offer a
* specific feature. If the application requests a feature that the hardware
* doesn't offer, SDL will always try to get the closest equivalent.
*
* For example, if you ask for float32 audio format, but the sound card only
* supports int16, SDL will set the hardware to int16. If you had set
* SDL_AUDIO_ALLOW_FORMAT_CHANGE, SDL will change the format in the `obtained`
* structure. If that flag was *not* set, SDL will prepare to convert your
* callback's float32 audio to int16 before feeding it to the hardware and
* will keep the originally requested format in the `obtained` structure.

* Load the audio data of a WAVE file into memory.
*
* Loading a WAVE file requires `src`, `spec`, `audio_buf` and `audio_len` to
* be valid pointers. The entire data portion of the file is then loaded into
* memory and decoded if necessary.
*
* If `freesrc` is non-zero, the data source gets automatically closed and
* freed before the function returns.
*
* Supported formats 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 mu-law (8 bits). Other formats are currently unsupported and
* cause an error.
*
* If this function succeeds, the pointer returned by it is equal to `spec`
* and the pointer to the audio data allocated by the function is written to
* `audio_buf` and its length in bytes to `audio_len`. The SDL_AudioSpec
* members `freq`, `channels`, and `format` are set to the values of the audio
* data in the buffer. The `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
* `audio_buf` when it is no longer used.
*
* Because of the underspecification of the .WAV 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 `src` being NULL), an appropriate error message will be
* set.
*
* It is required that the data source supports seeking.
*
* Example:
*
* ```c
* SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, &spec, &buf, &len);

*

*
* This function returns NULL if the .WAV file cannot be opened, uses

* a single SDL_free() will suffice.
*
* Returned language strings are in the format xx, where 'xx' is an ISO-639
* language specifier (such as "en" for English, "de" for German, etc).
* Country strings are in the format YY, where "YY" is an ISO-3166 country

* might be NULL if there's no specific guidance on them (so you might get {
* "en", "US" } for American English, but { "en", NULL } means "English
* language, generically"). Language strings are never NULL, except to
* terminate the array.
*
* Please note that not all of these strings are 2 characters; some are three
* or more.
*
* The returned list of locales are in the order of the user's preference. For
* example, a German citizen that is fluent in US English and knows enough
* Japanese to navigate around Tokyo might have a list like: { "de", "en_US",
* "jp", NULL }. Someone from England might prefer British English (where
* "color" is spelled "colour", etc), but will settle for anything like it: {
* "en_GB", "en", NULL }.
*
* This function returns NULL on error, including when the platform does not
* supply this information at all.
*
* This might be a "slow" call that has to query the operating system. It's
* best to ask for this once and save the results. However, this list can
* change, usually because the user has changed a system preference outside of
* your program; SDL will send an SDL_LOCALECHANGED event in this case, if
* possible, and you can call this function again to get an updated copy of

*
* See the Implementer's Guidelines for information about where this file
* should be located on your system and for more details of its use:
* http://www.khronos.org/registry/implementers_guide.pdf
*
* This file should be included as
* #include <KHR/khrplatform.h>
* by Khronos client API header files that use its types and defines.
*
* The types in khrplatform.h should only be used to define API-specific types.
*
* Types defined in khrplatform.h:
* khronos_int8_t signed 8 bit
* khronos_uint8_t unsigned 8 bit
* khronos_int16_t signed 16 bit
* khronos_uint16_t unsigned 16 bit
* khronos_int32_t signed 32 bit
* khronos_uint32_t unsigned 32 bit
* khronos_int64_t signed 64 bit
* khronos_uint64_t unsigned 64 bit
* khronos_intptr_t signed same number of bits as a pointer
* khronos_uintptr_t unsigned same number of bits as a pointer
* khronos_ssize_t signed size
* khronos_usize_t unsigned size
* khronos_float_t signed 32 bit floating point
* khronos_time_ns_t unsigned 64 bit time in nanoseconds
* khronos_utime_nanoseconds_t unsigned time interval or absolute time in
* nanoseconds
* khronos_stime_nanoseconds_t signed time interval in nanoseconds
* khronos_boolean_enum_t enumerated boolean type. This should
* only be used as a base type when a client API's boolean type is
* an enum. Client APIs which use an integer or other type for
* booleans cannot use this as the base type for their boolean.
*
* Tokens defined in khrplatform.h:
*
* KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
*
* KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
* KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.

* Dynamically load the Vulkan loader library.
*
* This should be called after initializing the video driver, but before

*
* It is fairly common for Vulkan applications to link with libvulkan instead
* of explicitly loading it at run time. This will work with SDL provided the
* application links to a dynamic library and both it and SDL use the same
* search path.
*
* If you specify a non-NULL `path`, an application should retrieve all of the
* Vulkan functions it uses from the dynamic library using
* SDL_Vulkan_GetVkGetInstanceProcAddr unless you can guarantee `path` points
* to the same vulkan loader library the application linked to.
*
* On Apple devices, if `path` is NULL, SDL will attempt to find the
* `vkGetInstanceProcAddr` address within all the Mach-O images of the current
* process. This is because it is fairly common for Vulkan applications to
* link with libvulkan (and historically MoltenVK was provided as a static
* library). If it is not found, on macOS, SDL will attempt to load
* `vulkan.framework/vulkan`, `libvulkan.1.dylib`,
* `MoltenVK.framework/MoltenVK`, and `libMoltenVK.dylib`, in that order. On
* iOS, SDL will attempt to load `libMoltenVK.dylib`. Applications using a
* dynamic framework or .dylib must ensure it is included in its application
* bundle.
*

* supported. Either do not link to the Vulkan loader or link to a dynamic

* Initialize the SDL library.
*
* SDL_Init() simply forwards to calling SDL_InitSubSystem(). Therefore, the
* two may be used interchangeably. Though for readability of your code
* SDL_InitSubSystem() might be preferred.
*
* The file I/O (for example: SDL_RWFromFile) and threading (SDL_CreateThread)
* subsystems are initialized by default. Message boxes
* (SDL_ShowSimpleMessageBox) also attempt to work without initializing the
* video subsystem, in hopes of being useful in showing an error dialog when
* SDL_Init fails. You must specifically initialize other subsystems if you
* use them in your application.
*
* Logging (such as SDL_Log) works without initialization, too.
*
* `flags` may be any of the following OR'd together:
*
* - `SDL_INIT_TIMER`: timer subsystem
* - `SDL_INIT_AUDIO`: audio subsystem
* - `SDL_INIT_VIDEO`: video subsystem; automatically initializes the events
* subsystem
* - `SDL_INIT_JOYSTICK`: joystick subsystem; automatically initializes the
* events subsystem
* - `SDL_INIT_HAPTIC`: haptic (force feedback) subsystem
* - `SDL_INIT_GAMECONTROLLER`: controller subsystem; automatically
* initializes the joystick subsystem
* - `SDL_INIT_EVENTS`: events subsystem
* - `SDL_INIT_EVERYTHING`: all of the above subsystems
* - `SDL_INIT_NOPARACHUTE`: compatibility; this flag is ignored
*
* Subsystem initialization is ref-counted, you must call SDL_QuitSubSystem()
* for each SDL_InitSubSystem() to correctly shutdown a subsystem manually (or
* call SDL_Quit() to force shutdown). If a subsystem is already loaded then
* this call will increase the ref-count and return.

* Atomic operations.
*
* IMPORTANT:
* If you are not an expert in concurrent lockless programming, you should
* only be using the atomic lock and reference counting functions in this
* file. In all other cases you should be protecting your data structures
* with full mutexes.
*
* The list of "safe" functions to use are:
* SDL_AtomicLock()
* SDL_AtomicUnlock()
* SDL_AtomicIncRef()
* SDL_AtomicDecRef()
*
* Seriously, here be dragons!
* ^^^^^^^^^^^^^^^^^^^^^^^^^^^
*
* You can find out a little more about lockless programming and the
* subtle issues that can arise here:
* http://msdn.microsoft.com/en-us/library/ee418650%28v=vs.85%29.aspx
*
* There's also lots of good information here:
* http://www.1024cores.net/home/lock-free-algorithms
* http://preshing.com/
*
* These operations may or may not actually be implemented using
* processor specific atomic operations. When possible they are
* implemented as true processor specific atomic operations. When that
* is not possible the are implemented using locks that *do* use the
* available atomic operations.
*
* All of the atomic operations that modify memory are full memory barriers.

* There are some quirks to looking up OpenGL functions that require some

*
* - On Windows, function pointers are specific to the current GL context;
* this means you need to have created a GL context and made it current
* before calling SDL_GL_GetProcAddress(). If you recreate your context or
* create a second context, you should assume that any existing function
* pointers aren't valid to use with it. This is (currently) a
* Windows-specific limitation, and in practice lots of drivers don't suffer
* this limitation, but it is still the way the wgl API is documented to
* work and you should expect crashes if you don't respect it. Store a copy
* of the function pointers that comes and goes with context lifespan.
* - On X11, function pointers returned by this function are valid for any
* context, and can even be looked up before a context is created at all.

* or verifying that the version of OpenGL you're using offers the function
* as core functionality.

/** \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

*
* The `mode` string is treated roughly the same as in a call to the C
* library's fopen(), even if SDL doesn't happen to use fopen() behind the
* scenes.
*
* Available `mode` strings:
*
* - "r": Open a file for reading. The file must exist.
* - "w": Create an empty file for writing. If a file with the same name
* already exists its content is erased and the file is treated as a new
* empty file.
* - "a": Append to a file. Writing operations append data at the end of the
* file. The file is created if it does not exist.
* - "r+": Open a file for update both reading and writing. The file must
* exist.
* - "w+": Create an empty file for both reading and writing. If a file with
* the same name already exists its content is erased and the file is
* treated as a new empty file.
* - "a+": Open a file for reading and appending. All writing operations are
* performed at the end of the file, protecting the previous content to be
* overwritten. You can reposition (fseek, rewind) the internal pointer to
* anywhere in the file for reading, but writing operations will move it
* back to the end of file. The file is created if it does not exist.
*
* **NOTE**: In order to open a file as a binary file, a "b" character has to
* be included in the `mode` string. This additional "b" character can either
* be appended at the end of the string (thus making the following compound
* modes: "rb", "wb", "ab", "r+b", "w+b", "a+b") or be inserted between the
* letter and the "+" sign for the mixed modes ("rb+", "wb+", "ab+").
* Additional characters may follow the sequence, although they should have no
* effect. For example, "t" is sometimes appended to make explicit the file is
* a text file.
*
* This function supports Unicode filenames, but they must be encoded in UTF-8
* format, regardless of the underlying operating system.
*
* As a fallback, SDL_RWFromFile() will transparently open a matching filename
* in an Android app's `assets`.

* Compose a custom blend mode for renderers.

*
* A blend mode controls how the pixels from a drawing operation (source) get
* combined with the pixels from the render target (destination). First, the
* components of the source and destination pixels get multiplied with their
* blend factors. Then, the blend operation takes the two products and
* calculates the result that will get stored in the render target.
*
* Expressed in pseudocode, it would look like this:
*
* ```c
* dstRGB = colorOperation(srcRGB * srcColorFactor, dstRGB * dstColorFactor);
* dstA = alphaOperation(srcA * srcAlphaFactor, dstA * dstAlphaFactor);
* ```
*
* Where the functions `colorOperation(src, dst)` and `alphaOperation(src,
* dst)` can return one of the following:
*
* - `src + dst`
* - `src - dst`
* - `dst - src`
* - `min(src, dst)`
* - `max(src, dst)`
*
* The red, green, and blue components are always multiplied with the first,
* second, and third components of the SDL_BlendFactor, respectively. The
* fourth component is not used.
*
* The alpha component is always multiplied with the fourth component of the
* SDL_BlendFactor. The other components are not used in the alpha
* calculation.
*
* Support for these blend modes varies for each renderer. To check if a
* specific SDL_BlendMode is supported, create a renderer and pass it to
* either SDL_SetRenderDrawBlendMode or SDL_SetTextureBlendMode. They will
* return with an error if the blend mode is not supported.
*
* This list describes the support of custom blend modes for each renderer in
* SDL 2.0.6. All renderers support the four blend modes listed in the
* SDL_BlendMode enumeration.
*
* - **direct3d**: Supports all operations with all factors. However, some
* factors produce unexpected results with `SDL_BLENDOPERATION_MINIMUM` and
* `SDL_BLENDOPERATION_MAXIMUM`.
* - **direct3d11**: Same as Direct3D 9.
* - **opengl**: Supports the `SDL_BLENDOPERATION_ADD` operation with all
* factors. OpenGL versions 1.1, 1.2, and 1.3 do not work correctly with SDL
* 2.0.6.
* - **opengles**: Supports the `SDL_BLENDOPERATION_ADD` operation with all
* factors. Color and alpha factors need to be the same. OpenGL ES 1
* implementation specific: May also support `SDL_BLENDOPERATION_SUBTRACT`
* and `SDL_BLENDOPERATION_REV_SUBTRACT`. May support color and alpha
* operations being different from each other. May support color and alpha
* factors being different from each other.
* - **opengles2**: Supports the `SDL_BLENDOPERATION_ADD`,
* `SDL_BLENDOPERATION_SUBTRACT`, `SDL_BLENDOPERATION_REV_SUBTRACT`
* operations with all factors.
* - **psp**: No custom blend mode support.
* - **software**: No custom blend mode support.
*
* Some renderers do not provide an alpha component for the default render
* target. The `SDL_BLENDFACTOR_DST_ALPHA` and
* `SDL_BLENDFACTOR_ONE_MINUS_DST_ALPHA` factors do not have an effect in this
* case.
*
* \param srcColorFactor the SDL_BlendFactor applied to the red, green, and
* blue components of the source pixels
* \param dstColorFactor the SDL_BlendFactor applied to the red, green, and
