###### (This is the legacy documentation for SDL2, the previous stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current stable version.) # SDL_Vulkan_GetDrawableSize Get the size of the window's underlying drawable dimensions in pixels. ## Header File Defined in [SDL_vulkan.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_vulkan.h) ## Syntax ```c void SDL_Vulkan_GetDrawableSize(SDL_Window * window, int *w, int *h); ``` ## Function Parameters | | | | | -------------------------- | ---------- | ---------------------------------------------------------------- | | [SDL_Window](SDL_Window) * | **window** | an [SDL_Window](SDL_Window) for which the size is to be queried. | | int * | **w** | Pointer to the variable to write the width to or NULL. | | int * | **h** | Pointer to the variable to write the height to or NULL. | ## Remarks This may differ from [SDL_GetWindowSize](SDL_GetWindowSize)() if we're rendering to a high-DPI drawable, i.e. the window was created with [`SDL_WINDOW_ALLOW_HIGHDPI`](SDL_WINDOW_ALLOW_HIGHDPI) on a platform with high-DPI support (Apple calls this "Retina"), and not disabled by the [`SDL_HINT_VIDEO_HIGHDPI_DISABLED`](SDL_HINT_VIDEO_HIGHDPI_DISABLED) hint. ## Version This function is available since SDL 2.0.6. ## See Also - [SDL_GetWindowSize](SDL_GetWindowSize) - [SDL_CreateWindow](SDL_CreateWindow) - [SDL_Vulkan_CreateSurface](SDL_Vulkan_CreateSurface) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryVulkan](CategoryVulkan)
