3、DescReq(zAddrType_t*dstAddr,uint16nwkAddr,uint16ProfileID,byteNumInClusters,cId_t*InClusterList,byteNumOutClusters,cId_t*OutClusterList,byteSecurityEnable){byte*pBuf=ZDP_TmpBuf;//nwkAddr+ProfileID+NumInClusters+NumOutClusters.bytei,len=2+2+1+1;//nwkAddr+ProfileID+NumInClusters+NumOutClusters.（网络地址，P

4、ROfileID，输入输出簇数量）len+=(NumInClusters+NumOutClusters)*sizeof(uint16);if(len>=ZDP_BUF_SZ-1){returnafStatus_MEM_FAIL;}*pBuf++=LO_UINT16(nwkAddr);//NWKAddrOfInterest*pBuf++=HI_UINT16(nwkAddr);*pBuf++=LO_UINT16(ProfileID);//ProfileID*pBuf++=HI_UINT16(ProfileID);*pBuf++=NumInClusters;//Inputclusterlistif(

5、NumInClusters){for(i=0;i

6、fileID，输入输出簇数量及其对应的簇的具体内容进行保存，保存在全局变量ZDP_TmpBuf中，并通过下面的函数fillAndSend函数发送returnfillAndSend(&ZDP_TransID,dstAddr,Match_Desc_req,len);//注意簇ID为Match_Desc_req }while(zdpMsgProcs[x].clusterID!=0xFFFF)//重点注意该函数及其结构体，里面有对应的根据簇ID进行相应处理的函数{if(zdpMsgProcs[x].clusterID==inMsg.clusterID)//注意该部分满足簇ID等于Match_Desc_

7、req，会执行对应的处理函 数{zdpMsgProcs[x].pFn(&inMsg);return;}x++;}上面重要的函数及其结构体的处理如下所示typedefstruct{uint16clusterID;pfnZDPMsgProcessorpFn;}zdpMsgProcItem_t;CONSTzdpMsgProcItem_tzdpMsgProcs[]={{NWK_addr_req,zdpPr
