include <search.h>

void insque(struct qelem ∗elem, struct qelem ∗pred);

void remque(struct qelem ∗elem);

insque() and remque() manipulate queues built from doubly linked lists. Each element in the queue must be in the following form:

struct qelem {
structqelem ∗q_forw;
structqelem ∗q_back;
charq_data[];
};

insque() inserts elem in a queue immediately after pred. remque() removes an entry elem from a queue.
