C Specification

The XrSpaceDiscoveryResultsMETA structure is defined as:

// Provided by XR_META_spatial_entity_discovery
typedef struct XrSpaceDiscoveryResultsMETA {
    XrStructureType                type;
    const void*                    next;
    uint32_t                       resultCapacityInput;
    uint32_t                       resultCountOutput;
    XrSpaceDiscoveryResultMETA*    results;
} XrSpaceDiscoveryResultsMETA;

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.

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

  • resultCountOutput is an output parameter containing the count of results for retrieval, or returns the required capacity in the case that resultCapacityInput is insufficient.

  • results is a pointer to an array of XrSpaceDiscoveryResultMETA structures to populate with the spaces retrieved, but can be NULL if resultCapacityInput is 0.

  • See the https://registry.khronos.org/OpenXR/specs/1.1/html/xrspec.html#fundamentals-buffer-size-parameters section for a detailed description of retrieving the required results size.

Description

The XrSpaceDiscoveryResultsMETA structure is used to retrieve all results from a Discovery operation.
