C Specification

The xrEnumerateSpaceSupportedComponentsFB function is defined as:

// Provided by XR_FB_spatial_entity
XrResult xrEnumerateSpaceSupportedComponentsFB(
    XrSpace                                     space,
    uint32_t                                    componentTypeCapacityInput,
    uint32_t*                                   componentTypeCountOutput,
    XrSpaceComponentTypeFB*                     componentTypes);

Parameters

Parameter Descriptions

  • space is the XrSpace handle to the spatial entity.

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

  • componentTypeCountOutput is a pointer to the count of componentTypes written, or a pointer to the required capacity in the case that componentTypeCapacityInput is insufficient.

  • componentTypes is a pointer to an array of XrSpaceComponentTypeFB values, but can be NULL if componentTypeCapacityInput is 0.

  • See Buffer Size Parameters chapter for a detailed description of retrieving the required componentTypes size.

Description

Lists any component types that an entity supports. The list of component types available for an entity depends on which extensions are enabled. Component types must not be enumerated unless the corresponding extension that defines them is also enabled.
