关于zcl库读写属性命令

读属性的命令也是由zcl相关的任务处理吗？看SampleLight例子里面有 void zclSampleLight_ProcessIncomingMsg( zclIncomingMsg_t *pInMsg)这个函数，应该是处理读写属性的吧？这个和on/off命令是不一样的处理方法，读写属性的命令怎么用，有没有读写属性的例子？

关于发送的读的命令

/*********************************************************************

* @param srcEP - Application's endpoint
* @param dstAddr - destination address

* @param direction - direction of the command
* @param seqNum - transaction sequence number

* @return ZSuccess if OK
*/

uint16 clusterID, zclReadCmd_t *readCmd,

{
uint16 dataLen;
uint8 *buf;
uint8 *pBuf;
ZStatus_t status;

dataLen = readCmd->numAttr * 2; // Attribute ID

buf = zcl_mem_alloc( dataLen );
if ( buf != NULL )
{
uint8 i;

// Load the buffer - serially
pBuf = buf;
for (i = 0; i < readCmd->numAttr; i++)
{
*pBuf++ = LO_UINT16( readCmd->attrID[i] );

}

direction, disableDefaultRsp, 0, seqNum, dataLen, buf );
zcl_mem_free( buf );
}
else
{
status = ZMemError;
}

return ( status );
}

关于处理读属性的命令
