###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!) # SDL_ClaimWindowForGPUDevice Claims a window, creating a swapchain structure for it. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_gpu.h) ## Syntax ```c bool SDL_ClaimWindowForGPUDevice( SDL_GPUDevice *device, SDL_Window *window); ``` ## Function Parameters | | | | | -------------------------------- | ---------- | ---------------------------- | | [SDL_GPUDevice](SDL_GPUDevice) * | **device** | a GPU context. | | [SDL_Window](SDL_Window) * | **window** | an [SDL_Window](SDL_Window). | ## Return Value (bool) Returns true on success, otherwise false. ## Remarks This must be called before [SDL_AcquireGPUSwapchainTexture](SDL_AcquireGPUSwapchainTexture) is called using the window. The swapchain will be created with [SDL_GPU_SWAPCHAINCOMPOSITION_SDR](SDL_GPU_SWAPCHAINCOMPOSITION_SDR) and [SDL_GPU_PRESENTMODE_VSYNC](SDL_GPU_PRESENTMODE_VSYNC). If you want to have different swapchain parameters, you must call [SDL_SetGPUSwapchainParameters](SDL_SetGPUSwapchainParameters) after claiming the window. ## Version This function is available since SDL 3.0.0. ## See Also - [SDL_AcquireGPUSwapchainTexture](SDL_AcquireGPUSwapchainTexture) - [SDL_ReleaseWindowFromGPUDevice](SDL_ReleaseWindowFromGPUDevice) - [SDL_WindowSupportsGPUPresentMode](SDL_WindowSupportsGPUPresentMode) - [SDL_WindowSupportsGPUSwapchainComposition](SDL_WindowSupportsGPUSwapchainComposition) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryGPU](CategoryGPU)
