// Provided by XR_FB_eye_tracking_social

    const XrEyeTrackerCreateInfoFB*             createInfo,

Parameters

Parameter Descriptions

Description

If the system does not support eye tracking, the runtime must return XR_ERROR_FEATURE_UNSUPPORTED from xrCreateEyeTrackerFB. In this case, the runtime must return XR_FALSE for XrSystemEyeTrackingPropertiesFB::supportsEyeTracking when the function xrGetSystemProperties is called, so that the application can avoid creating an eye tracker.
