C Specification

The XrSpatialComponentParentListEXT structure is defined as:

// Provided by XR_EXT_spatial_entity
typedef struct XrSpatialComponentParentListEXT {
    XrStructureType          type;
    void*                    next;
    uint32_t                 parentCount;
    XrSpatialEntityIdEXT*    parents;
} XrSpatialComponentParentListEXT;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.

  • parentCount is a uint32_t describing the count of elements in the parents array.

  • parents is an array of XrSpatialEntityIdEXT.

Description

The runtime must return XR_ERROR_VALIDATION_FAILURE from xrQuerySpatialComponentDataEXT if XrSpatialComponentParentListEXT is in the next chain of XrSpatialComponentDataQueryResultEXT::next but XrSpatialComponentDataQueryConditionEXT::componentTypeCount is not zero and XR_SPATIAL_COMPONENT_TYPE_PARENT_EXT is not included in XrSpatialComponentDataQueryConditionEXT::componentTypes.

The runtime must return XR_ERROR_SIZE_INSUFFICIENT from xrQuerySpatialComponentDataEXT if parentCount is less than XrSpatialComponentDataQueryResultEXT::entityIdCountOutput.
