Get the size of a window's client area.
Defined in SDL_video.h
void SDL_GetWindowSize(SDL_Window * window, int *w,
int *h);
SDL_Window * | window | the window to query the width and height from. |
int * | w | a pointer filled in with the width of the window, in screen coordinates, may be NULL. |
int * | h | a pointer filled in with the height of the window, in screen coordinates, may be NULL. |
NULL can safely be passed as the w
or h
parameter if the width or height value is not desired.
The window size in screen coordinates may differ from the size in pixels, if the window was created with SDL_WINDOW_ALLOW_HIGHDPI
on a platform with high-dpi support (e.g. iOS or macOS). Use SDL_GL_GetDrawableSize(), SDL_Vulkan_GetDrawableSize(), or SDL_GetRendererOutputSize() to get the real client area size in pixels.
This function is available since SDL 2.0.0.
