#define TAILQ_ENTRY(type)                                               \
struct {                                                                \
        struct type *tqe_next;  /* next element */                      \
        struct type **tqe_prev; /* address of previous next element */  \
}
我想问一下像这样的结构是干什么用的，是组织一个链表吗？谢谢了！
