C Specification

The XrSpatialAnchorsQueryCompletionML structure is defined as:

// Provided by XR_ML_spatial_anchors_storage
typedef struct XrSpatialAnchorsQueryCompletionML {
    XrStructureType    type;
    void*              next;
    XrResult           futureResult;
    uint32_t           uuidCapacityInput;
    uint32_t           uuidCountOutput;
    XrUuidEXT*         uuids;
} XrSpatialAnchorsQueryCompletionML;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain.

  • futureResult is the XrResult of the asynchronous operation.

  • uuidCapacityInput is the capacity of the uuids array, or 0 to indicate a request to retrieve the required capacity.

  • uuidCountOutput is the number of elements populated in uuids, or the required capacity in the case that uuidCapacityInput is insufficient.

  • uuids is an array of XrUuidEXT.
