Get information about the desktop's display mode.
const SDL_DisplayMode* SDL_GetDesktopDisplayMode(SDL_DisplayID displayID);
displayID | the instance ID of the display to query |
Returns a pointer to the desktop display mode or NULL on error; call SDL_GetError() for more information.
There's a difference between this function and SDL_GetCurrentDisplayMode() when SDL runs fullscreen and has changed the resolution. In that case this function will return the previous native display mode, and not the current display mode.
This function is available since SDL 3.0.0.
SDL_DisplayMode dm;if (SDL_GetDesktopDisplayMode(0, &dm) != 0) {
"SDL_GetDesktopDisplayMode failed: %s", SDL_GetError());
SDL_Log(return 1;
}
