C Specification

The XrFutureCompletionBaseHeaderEXT structure is defined as:

// Provided by XR_EXT_future
typedef struct XrFutureCompletionBaseHeaderEXT {
    XrStructureType    type;
    void*              next;
    XrResult           futureResult;
} XrFutureCompletionBaseHeaderEXT;

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 XrResult of the async operation associated with future passed to the completion function.

Description

XrFutureCompletionBaseHeaderEXT is a base header for the result of a future completion function.

Valid Usage (Implicit)

  • The XR_EXT_future extension must be enabled prior to using XrFutureCompletionBaseHeaderEXT

  • type must be one of the following XrStructureType values: XR_TYPE_CREATE_SPATIAL_ANCHORS_COMPLETION_ML, XR_TYPE_CREATE_SPATIAL_CONTEXT_COMPLETION_EXT, XR_TYPE_CREATE_SPATIAL_DISCOVERY_SNAPSHOT_COMPLETION_EXT, XR_TYPE_CREATE_SPATIAL_PERSISTENCE_CONTEXT_COMPLETION_EXT, XR_TYPE_FUTURE_COMPLETION_EXT, XR_TYPE_PERSIST_SPATIAL_ENTITY_COMPLETION_EXT, XR_TYPE_SENSE_DATA_QUERY_COMPLETION_BD, XR_TYPE_SPATIAL_ANCHOR_CREATE_COMPLETION_BD, XR_TYPE_SPATIAL_ANCHORS_DELETE_COMPLETION_ML, XR_TYPE_SPATIAL_ANCHORS_PUBLISH_COMPLETION_ML, XR_TYPE_SPATIAL_ANCHORS_QUERY_COMPLETION_ML, XR_TYPE_SPATIAL_ANCHORS_UPDATE_EXPIRATION_COMPLETION_ML, XR_TYPE_UNPERSIST_SPATIAL_ENTITY_COMPLETION_EXT, XR_TYPE_WORLD_MESH_REQUEST_COMPLETION_ML, XR_TYPE_WORLD_MESH_STATE_REQUEST_COMPLETION_ML

  • next must be NULL or a valid pointer to the next structure in a structure chain

  • futureResult must be a valid XrResult value
