How to get client area size of window in SDL2

Question

How can I get the resolution of window without taking border into account in SDL2? I need the function just like GetClientRect in WinAPI, but it seems like there is no equal function in SDL2.

Using SDL_GetWindowSize, you can grab the width and height of the client window.

SDL_Window* window = SDL_CreateWindow("Window", 0, 0, 800, 600, 0);
int width;
int height;
SDL_GetWindowSize(window, &width, &height);

width = 800, height = 600
