# Simple DirectMedia Layer (SDL) Version 2.0
https://www.libsdl.org/
Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.
More extensive documentation is available in the docs directory, starting
with README.md
Enjoy!

However, there's a chance (on older hardware, or on systems under heavy load),

receive SDL_RENDER_DEVICE_RESET).

KMSDRM on *BSD
==================================================
KMSDRM is supported on FreeBSD and OpenBSD. DragonFlyBSD is not tested yet, but should work. NetBSD isn't supported yet because the application will crash when creating the KMSDRM screen.
WSCONS support has been brought back, but only as an input backend. It will not be brought back as a video backend to ease maintenance.
OpenBSD note: Note that the video backend assumes that the user has read/write permissions to the /dev/drm* devices.

2. It has mouse support.
3. Accent input is supported.
4. Compose keys are supported.
5. AltGr and Meta Shift keys work as intended.
Partially working or no input on OpenBSD/NetBSD.
==================================================
The WSCONS input backend needs read/write access to the /dev/wskbd* devices, without which it will not work properly. /dev/wsmouse must also be read/write accessible, otherwise mouse input will not work.
Partially working or no input on FreeBSD.
==================================================
The evdev devices are only accessible to the root user by default. Edit devfs rules to allow access to such devices. The /dev/kbd* devices are also only accessible to the root user by default. Edit devfs rules to allow access to such devices.

Using SDL with Microsoft Visual C++
===================================
### by [Lion Kimbro](mailto:snowlion@sprynet.com) with additions by [James Turk](mailto:james@conceptofzero.net)
You can either use the precompiled libraries from the [SDL](https://www.libsdl.org/download.php) web site, or you can build SDL
yourself.
### Building SDL
0. To build SDL, your machine must, at a minimum, have the DirectX9.0c SDK installed. It may or may not be retrievable from
the [Microsoft](https://www.microsoft.com) website, so you might need to locate it [online](https://duckduckgo.com/?q=directx9.0c+sdk+download&t=h_&ia=web).
_Editor's note: I've been able to successfully build SDL using Visual Studio 2019 **without** the DX9.0c SDK_
1. Open the Visual Studio solution file at `./VisualC/SDL.sln`.
2. Your IDE will likely prompt you to upgrade this solution file to whatever later version of the IDE you're using. In the `Retarget Projects` dialog,
all of the affected project files should be checked allowing you to use the latest `Windows SDK Version` you have installed, along with
the `Platform Toolset`.
If you choose *NOT* to upgrade to use the latest `Windows SDK Version` or `Platform Toolset`, then you'll need the `Visual Studio 2010 Platform Toolset`.
3. Build the `.dll` and `.lib` files by right clicking on each project in turn (Projects are listed in the _Workspace_
panel in the _FileView_ tab), and selecting `Build`.
You may get a few warnings, but you should not get any errors.
Later, we will refer to the following `.lib` and `.dll` files that have just been generated:
- `./VisualC/Win32/Debug/SDL2.dll` or `./VisualC/Win32/Release/SDL2.dll`
- `./VisualC/Win32/Debug/SDL2.lib` or `./VisualC/Win32/Release/SDL2.lib`
- `./VisualC/Win32/Debug/SDL2main.lib` or `./VisualC/Win32/Release/SDL2main.lib`
_Note for the `x64` versions, just replace `Win32` in the path with `x64`_
### Creating a Project with SDL
- Create a project as a `Win32 Application`.
- Create a C++ file for your project.
- Set the C runtime to `Multi-threaded DLL` in the menu:
`Project|Settings|C/C++ tab|Code Generation|Runtime Library `.
- Add the SDL `include` directory to your list of includes in the menu:
`Project|Settings|C/C++ tab|Preprocessor|Additional include directories `
*VC7 Specific: Instead of doing this, I find it easier to add the
include and library directories to the list that VC7 keeps. Do this by
selecting Tools|Options|Projects|VC++ Directories and under the "Show
Directories For:" dropbox select "Include Files", and click the "New
Directory Icon" and add the [SDLROOT]\\include directory (e.g. If you
installed to c:\\SDL\\ add c:\\SDL\\include). Proceed to change the
dropbox selection to "Library Files" and add [SDLROOT]\\lib.*
The "include directory" I am referring to is the `./include` folder.
Now we're going to use the files that we had created earlier in the *Build SDL* step.
Copy the following file into your Project directory:
- `SDL2.dll`
Add the following files to your project (It is not necessary to copy them to your project directory):
- `SDL2.lib`
- `SDL2main.lib`
To add them to your project, right click on your project, and select
`Add files to project`.
**Instead of adding the files to your project, it is more desirable to add them to the linker options: Project|Properties|Linker|Command Line
and type the names of the libraries to link with in the "Additional Options:" box. Note: This must be done for each build configuration
(e.g. Release,Debug).**
### Hello SDL2
Here's a sample SDL snippet to verify everything is setup in your IDE:
```
#include "SDL.h"
int main( int argc, char* argv[] )
{
const int WIDTH = 640;
const int HEIGHT = 480;
SDL_Window* window = NULL;
SDL_Renderer* renderer = NULL;
SDL_Init(SDL_INIT_VIDEO);
window = SDL_CreateWindow("SDL2 Test", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, WIDTH, HEIGHT, SDL_WINDOW_SHOWN);
renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
SDL_DestroyRenderer(renderer);
SDL_DestroyWindow(window);
SDL_Quit();
return 0;
}
```
### That's it!
I hope that this document has helped you get through the most difficult part of using the SDL: installing it.
Suggestions for improvements should be posted to the [Github Issues](https://github.com/libsdl-org/SDL/issues).

PS Vita
=======
SDL port for the Sony Playstation Vita ans Sony Playstation TV
Credit to
* xerpi and rsn8887 for initial (vita2d) port
* vitasdk/dolcesdk devs
* CBPS discord (Namely Graphene and SonicMastr)
Building
--------
To build for the PSP, make sure you have vitasdk and cmake installed and run:
```
cmake -S. -Bbuild -DCMAKE_TOOLCHAIN_FILE=${VITASDK}/share/vita.toolchain.cmake -DCMAKE_BUILD_TYPE=Release
cmake --build build
cmake --install build
```
Notes
-----
* There are two renderers: native gxm and pigs-in-a-blanket gles2.
By default gxm one is used. gles2 renderer is slow and only usable if you want to bind SDL_Texture to GL context.
You can create gles2 renderer by using hint or `1` as a renderer index in `SDL_CreateRenderer`.
* By default SDL emits mouse events for touch events on every touchscreen.
Vita has two touchscreens, so it's recommended to use `SDL_SetHint(SDL_HINT_TOUCH_MOUSE_EVENTS, "0");` and handle touch events instead.
* Support for L2/R2/R3/R3 buttons, haptic feedback and gamepad led only available on PSTV, or when using external ds4 gamepad on vita.

* This function initializes the subsystems specified by \c flags

*
* 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)

* (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.

* This function is a legacy means of opening the audio device.
*
* When filling in the desired audio spec structure,
* - \c desired->freq should be the desired audio frequency in samples-per-
* second.
* - \c desired->format should be the desired audio format.
* - \c desired->samples is the desired size of the audio buffer, in
* samples. 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 yield faster response time,
* but can lead to underflow if the application is doing heavy processing
* and cannot fill the audio buffer in time. A stereo sample consists of
* both right and left channels in LR ordering.
* Note that the number of samples is directly related to time by the
* following formula: \code ms = (samples*1000)/freq \endcode
* - \c desired->size is the size in bytes of the audio buffer, and is
* calculated by SDL_OpenAudio().
* - \c desired->silence is the value used to set the buffer to silence,
* and is calculated by SDL_OpenAudio().
* - \c 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_LockAudio()
* and SDL_UnlockAudio() 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).
* - \c desired->userdata is passed as the first parameter to your callback
* function. If you passed a NULL callback, this value is ignored.
* This function remains for compatibility with SDL 1.2, but also because it's
* slightly easier to use than the new functions in SDL 2.0. The new, more
* powerful, and preferred way to do this is SDL_OpenAudioDevice().
*
* The audio device starts out playing silence when it's opened, and should
* be enabled for playing by calling \c SDL_PauseAudio(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.
* This function is roughly equivalent to:
*
* ```c++
* SDL_OpenAudioDevice(NULL, 0, desired, obtained, SDL_AUDIO_ALLOW_ANY_CHANGE);
* ```
*
* With two notable exceptions:
*
* - If `obtained` is NULL, we use `desired` (and allow no changes), which
* means desired will be modified to have the correct values for silence,
* etc, and SDL will convert any differences between your app's specific
* request and the hardware behind the scenes.
* - The return value is always success or failure, and not a device ID, which
* means you can only have one device open at a time with this function.
*
* \param desired an SDL_AudioSpec structure representing the desired output
* format. Please refer to the SDL_OpenAudioDevice documentation
* for details on how to prepare this structure.
* \param obtained an SDL_AudioSpec structure filled in with the actual

* 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

* structure.
*
* If your application can only handle one specific data format, pass a zero
* for `allowed_changes` and let SDL transparently handle any differences.
*
* 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.

* race conditions between your callback and other threads without fully
* pausing playback with SDL_LockAudioDevice(). For more information about the
* callback, see SDL_AudioSpec.

* SDL_BuildAudioCVT(), and should be \c cvt->len*cvt->len_mult bytes long.
* The data conversion may go through several passes; any given pass may
* possibly temporarily increase the size of the data. For example, SDL might
* expand 16-bit data to 32 bits before resampling to a lower frequency,
* shrinking the data size after having grown it briefly. Since the supplied
* buffer will be both the source and destination, converting as necessary
* in-place, the application must allocate a buffer that will fully contain
* the data during its largest conversion pass. After SDL_BuildAudioCVT()
* returns, the application should set the `cvt->len` field to the size, in
* bytes, of the source data, and allocate a buffer that is
* `cvt->len * cvt->len_mult` bytes long for the `buf` field.
*
* \return 0 on success or -1 if \c cvt->buf is NULL.
* The source data should be copied into this buffer before the call to
* SDL_ConvertAudio(). Upon successful return, this buffer will contain the

* The result of the blend mode operation will be:
* dstRGB = dstRGB * dstColorFactor colorOperation srcRGB * srcColorFactor
* and
* dstA = dstA * dstAlphaFactor alphaOperation srcA * srcAlphaFactor
* 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

*
* - `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_BlendMode enumeration.
*

* - **direct3d11**: Supports all operations with all factors. However, some
* factors produce unexpected results with `SDL_BLENDOPERATION_MINIMUM` and
* `SDL_BLENDOPERATION_MAXIMUM`.
* - **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
