The insque() and remque() functions manipulate queues built from doubly linked lists. Each element in the queue must be in the following form:
struct qelem { struct qelem *q_forw; struct qelem *q_back; char q_data[]; };
The insque() function inserts elem in a queue immediately after pred. The remque() function removes an entry elem from a queue.
