C Specification

The XrSemanticLabelsFB structure is defined as:

// Provided by XR_FB_scene
typedef struct XrSemanticLabelsFB {
    XrStructureType    type;
    const void*        next;
    uint32_t           bufferCapacityInput;
    uint32_t           bufferCountOutput;
    char*              buffer;
} XrSemanticLabelsFB;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain, such as XrSemanticLabelsSupportInfoFB.

  • bufferCapacityInput is the capacity of the buffer array, in bytes, or 0 to indicate a request to retrieve the required capacity.

  • bufferCountOutput is the count of bytes written, or the required capacity in the case that bufferCapacityInput is insufficient.

  • buffer is a pointer to an array of bytes, but can be NULL if bufferCapacityInput is 0. Multiple labels represented by raw string, separated by a comma without spaces.

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

Description

This structure is used by the xrGetSpaceSemanticLabelsFB function to provide the application with the intended usage of the spatial entity.
