双向循环链表节点的插入可以在头部或者指定节点后面进行。c在指定节点后插入LITEOSSECALWINLINESTATICINLINEVOIDLOSListAdd(LOSDLLISTlist,LOSDLLISTnode){node>pstNextlist>pstNext;node>pstPrevlist;list>pstNext>pstPrevnode;list>pstNextnode;}在链表头插入LITEOSSECALWINLINESTATICINLINEVOIDLOSListHeadInsert(LOSDLLISTlist,LOSDLLISTnode){LOSListAdd(list,node);}

可以使用protoFromFile方法加载.proto文件以构建协议消息体：javascriptletcontextGlobalContext.getContext().getObject("context");varbuilderprotobuf.protoFromFile('userproto.proto',(error,builder)>{if(error){console.error('protobufcodeccatcherror:'+error);return;}varUserLoginResponsebuilder.build("com.user.UserLoginResponse");varmsgnewUserLoginResponse(this.userLogin);vararrayBuffermsg.toArrayBuffer();vardecodeMsgUserLoginResponse.decode(arrayBuffer);console.log("protobufdecode:"+JSON.stringify(decodeMsg));},null,context.resourceManager);
