Function otBorderAgentGetMeshCoPServiceTxtData 

pub unsafe extern "C" fn otBorderAgentGetMeshCoPServiceTxtData(
    aInstance: *mut otInstance,
    aTxtData: *mut otBorderAgentMeshCoPServiceTxtData,
) -> otError

Gets the MeshCoP service TXT data.

The generated TXT data includes a subset of keys (depending on the device’s current state and whether features are enabled) as specified in the documentation of the OT_BORDER_AGENT_MESHCOP_SERVICE_TXT_DATA_MAX_LENGTH constant. Notably, if OPENTHREAD_CONFIG_BORDER_AGENT_MESHCOP_SERVICE_ENABLE is enabled and otBorderAgentSetVendorTxtData() was used to set extra vendor-specific TXT data bytes, those vendor-specified TXT data bytes are NOT included in the TXT data returned by this function.

@param[in] aInstance A pointer to an OpenThread instance. @param[out] aTxtData A pointer to a MeshCoP Service TXT data struct to get the data.

@retval OT_ERROR_NONE If successfully retrieved the Border Agent MeshCoP Service TXT data. @retval OT_ERROR_NO_BUFS If the buffer in @p aTxtData doesn’t have enough size.
