#include "SDL3/SDL.h"

SDL_PropertiesID SDL_GetDisplayProperties(SDL_DisplayID displayID);

The following read-only properties are provided by SDL:

· SDL_PROP_DISPLAY_HDR_ENABLED_BOOLEAN :
 true if the display has HDR headroom above the SDR white point. This is
 for informational and diagnostic purposes only, as not all platforms
 provide this information at the display level.

On KMS/DRM:

· SDL_PROP_DISPLAY_KMSDRM_PANEL_ORIENTATION_NUMBER :
 the "panel orientation" property for the display in degrees of clockwise
 rotation. Note that this is provided only as a hint, and the application
 is responsible for any coordinate transformations needed to conform to
 the requested display orientation.

displayID

the instance ID of the display to query.

( SDL_PropertiesID ) Returns a valid property ID on success or 0 on failure; call SDL_GetError () for more information.

This function should only be called on the main thread.

This function is available since SDL 3.2.0.
