c - 队列.h : how to create list of lists/queue of queues/similar combinations?

Question

Man page BSD的queue.h清楚地显示了如何创建单链表/双链表/尾队列，但我不知道如何创建例如列表列表或队列队列？特别是，如何处理从属查询的声明和初始化？

我尝试了什么:

//element of slave queue
struct slaveentry {
    STAILQ_ENTRY(slaveentry) pts;   //pointers
    /*data here*/
    } *selt;                        //element of queue

//element of master queue
struct masterentry {
    STAILQ_ENTRY(masterentry) pts;  //pointers
    struct slavehead *slave;        //pointer to slave queue head
    /*data here*/
    } *melt;                        //element of queue

//initialization of sturctures
STAILQ_HEAD(masterhead, masterentry) big_queue = STAILQ_HEAD_INITIALIZER(big_queue);
STAILQ_INIT(&big_queue);

//what's next? I don't know, maybe some sort of the following
STAILQ_HEAD(slavehead, slaveentry) small_queue = STAILQ_HEAD_INITIALIZER(small_queue);
STAILQ_INIT(&small_queue);
