Get the properties associated with a renderer.
Defined in <SDL3/SDL_render.h>
SDL_PropertiesID SDL_GetRendererProperties(SDL_Renderer *renderer);| SDL_Renderer * | renderer | the rendering context. |
(SDL_PropertiesID) Returns a valid property ID on success or 0 on failure; call SDL_GetError() for more information.
The following read-only properties are provided by SDL:
SDL_PROP_RENDERER_NAME_STRING: the name of the rendering driverSDL_PROP_RENDERER_WINDOW_POINTER: the window where rendering is displayed, if anySDL_PROP_RENDERER_SURFACE_POINTER: the surface where rendering is displayed, if this is a software renderer without a windowSDL_PROP_RENDERER_VSYNC_NUMBER: the current vsync settingSDL_PROP_RENDERER_MAX_TEXTURE_SIZE_NUMBER: the maximum texture width and heightSDL_PROP_RENDERER_TEXTURE_FORMATS_POINTER: a (const SDL_PixelFormat *) array of pixel formats, terminated with SDL_PIXELFORMAT_UNKNOWN, representing the available texture formats for this renderer.SDL_PROP_RENDERER_OUTPUT_COLORSPACE_NUMBER: an SDL_Colorspace value describing the colorspace for output to the display, defaults to SDL_COLORSPACE_SRGB.SDL_PROP_RENDERER_HDR_ENABLED_BOOLEAN: true if the output colorspace is SDL_COLORSPACE_SRGB_LINEAR and the renderer is showing on a display with HDR enabled. This property can change dynamically when SDL_EVENT_WINDOW_HDR_STATE_CHANGED is sent.SDL_PROP_RENDERER_SDR_WHITE_POINT_FLOAT: the value of SDR white in the SDL_COLORSPACE_SRGB_LINEAR colorspace. When HDR is enabled, this value is automatically multiplied into the color scale. This property can change dynamically when SDL_EVENT_WINDOW_HDR_STATE_CHANGED is sent.SDL_PROP_RENDERER_HDR_HEADROOM_FLOAT: the additional high dynamic range that can be displayed, in terms of the SDR white point. When HDR is not enabled, this will be 1.0. This property can change dynamically when SDL_EVENT_WINDOW_HDR_STATE_CHANGED is sent.With the direct3d renderer:
SDL_PROP_RENDERER_D3D9_DEVICE_POINTER: the IDirect3DDevice9 associated with the rendererWith the direct3d11 renderer:
SDL_PROP_RENDERER_D3D11_DEVICE_POINTER: the ID3D11Device associated with the rendererSDL_PROP_RENDERER_D3D11_SWAPCHAIN_POINTER: the IDXGISwapChain1 associated with the renderer. This may change when the window is resized.With the direct3d12 renderer:
SDL_PROP_RENDERER_D3D12_DEVICE_POINTER: the ID3D12Device associated with the rendererSDL_PROP_RENDERER_D3D12_SWAPCHAIN_POINTER: the IDXGISwapChain4 associated with the renderer.SDL_PROP_RENDERER_D3D12_COMMAND_QUEUE_POINTER: the ID3D12CommandQueue associated with the rendererWith the vulkan renderer:
SDL_PROP_RENDERER_VULKAN_INSTANCE_POINTER: the VkInstance associated with the rendererSDL_PROP_RENDERER_VULKAN_SURFACE_NUMBER: the VkSurfaceKHR associated with the rendererSDL_PROP_RENDERER_VULKAN_PHYSICAL_DEVICE_POINTER: the VkPhysicalDevice associated with the rendererSDL_PROP_RENDERER_VULKAN_DEVICE_POINTER: the VkDevice associated with the rendererSDL_PROP_RENDERER_VULKAN_GRAPHICS_QUEUE_FAMILY_INDEX_NUMBER: the queue family index used for renderingSDL_PROP_RENDERER_VULKAN_PRESENT_QUEUE_FAMILY_INDEX_NUMBER: the queue family index used for presentationSDL_PROP_RENDERER_VULKAN_SWAPCHAIN_IMAGE_COUNT_NUMBER: the number of swapchain images, or potential frames in flight, used by the Vulkan rendererWith the gpu renderer:
SDL_PROP_RENDERER_GPU_DEVICE_POINTER: the SDL_GPUDevice associated with the rendererIt is safe to call this function from any thread.
This function is available since SDL 3.2.0.
