C Specification

The xrGetSpaceUuidFB function is defined as:

// Provided by XR_FB_spatial_entity
XrResult xrGetSpaceUuidFB(
    XrSpace                                     space,
    XrUuidEXT*                                  uuid);

Parameters

Parameter Descriptions

  • space is the XrSpace handle of a spatial entity.

  • uuid is an output parameter pointing to the entity’s UUID.

If this space was previously created as a spatial anchor, uuid must be equal to the XrEventDataSpatialAnchorCreateCompleteFB::uuid in the event corresponding to the creation of that space. Subsequent calls to xrGetSpaceUuidFB using the same XrSpace must return the same XrUuidEXT.
