Function SDL_ClaimWindowForGPUDevice 

pub unsafe extern "C" fn SDL_ClaimWindowForGPUDevice(
    device: *mut SDL_GPUDevice,
    window: *mut SDL_Window,
) -> bool

Claims a window, creating a swapchain structure for it.

This must be called before SDL_AcquireGPUSwapchainTexture is called using the window. You should only call this function from the thread that created the window.

The swapchain will be created with SDL_GPU_SWAPCHAINCOMPOSITION_SDR and SDL_GPU_PRESENTMODE_VSYNC. If you want to have different swapchain parameters, you must call SDL_SetGPUSwapchainParameters after claiming the window.

Parameters

• device: a GPU context.
• window: an SDL_Window.

Return value

Returns true on success, or false on failure; call SDL_GetError() for more information.

Thread safety

This function should only be called from the thread that created the window.

Availability

This function is available since SDL 3.2.0.
