Get information about the desktop's display mode.
int SDL_GetDesktopDisplayMode(int displayIndex, SDL_DisplayMode * mode);
displayIndex |
the index of the display to query |
mode |
an SDL_DisplayMode structure filled in with the current display mode |
Returns 0 on success or a negative error code on failure; 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.
SDL_DisplayMode dm;if (SDL_GetDesktopDisplayMode(0, &dm) != 0) {
"SDL_GetDesktopDisplayMode failed: %s", SDL_GetError());
SDL_Log(return 1;
}
