sdlGetCurrentRenderOutputSize function render

bool sdlGetCurrentRenderOutputSize(Pointer<SdlRenderer> renderer, Pointer<Int32> w, Pointer<Int32> h)

Get the current output size in pixels of a rendering context.

If a rendering target is active, this will return the size of the rendering target in pixels, otherwise return the value of SDL_GetRenderOutputSize().

Rendering target or not, the output will be adjusted by the current logical presentation state, dictated by SDL_SetRenderLogicalPresentation().

\param renderer the rendering context. \param w a pointer filled in with the current width. \param h a pointer filled in with the current height. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.2.0.
