SDL_WINDOWPOS_UNDEFINED_DISPLAY(3) SDL3 FUNCTIONS SDL_WINDOWPOS_UNDEFINED_DISPLAY(3)

SDL_WINDOWPOS_UNDEFINED_DISPLAY - Used to indicate that you don't care what the window position is.

Defined in SDL3/SDL_video.h

#include "SDL3/SDL.h"
#define SDL_WINDOWPOS_UNDEFINED_DISPLAY(X)  (SDL_WINDOWPOS_UNDEFINED_MASK|(X))

If you _really_ don't care,

SDL_WINDOWPOS_UNDEFINED
is the same, but always uses the primary display instead of specifying one.

This macro is available since SDL 3.2.0.
