Contents
Syntax
void SDL_Vulkan_GetDrawableSize(SDL_Window* window,
int* w,
int* h);
Function Parameters
window |
SDL_Window for which the size is to be queried |
w |
Pointer to the variable to write the width to or NULL |
h |
Pointer to the variable to write the height to or NULL |
Code Examples
int width;
int height;
SDL_Vulkan_GetDrawableSize(window, &width, &height);
Remarks
This may differ from SDL_GetWindowSize if we're rendering to a high-DPI drawable, i.e. the window was created with 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 hint.
Version
This function is available in SDL 2.0.8
