C Specification

The application can call the xrGetSerializedSceneFragmentDataMSFT function to read the binary data of a serialized scene fragment from the XrSceneMSFT handle. This function follows the two-call idiom for filling the buffer.

The xrGetSerializedSceneFragmentDataMSFT function is defined as:

XrResult xrGetSerializedSceneFragmentDataMSFT(
    XrSceneMSFT                                 scene,
    const XrSerializedSceneFragmentDataGetInfoMSFT* getInfo,
    uint32_t                                    countInput,
    uint32_t*                                   readOutput,
    uint8_t*                                    buffer);
