insque, remque — insert/remove element from a queue
SYNOPSIS
struct qelem {
struct qelem *q_forw;
struct qelem *q_back;
char q_data[];
};
insque((caddr_t) struct qelem *elem, (caddr_t) struct qelem *pred);
remque((caddr_t) struct qelem *elem);
DESCRIPTION
The insque() and remque() functions manipulate queues built from doubly
linked lists. Each element in the queue must be in the form of “struct
qelem”. The function insque() inserts elem in a queue immediately after
pred; remque() removes an entry elem from a queue.
