INSQUE(3)                 386BSD Programmer's Manual                 INSQUE(3)

NAME
     insque, remque - insert/remove element from a circular queue

SYNOPSIS
     struct qelem {
          struct qelem *q_forw;
          struct qelem *q_back;
          char q_data[];
     };
     struct qelem *
     insque(struct qelem *entry, struct qelem *pred)

     struct qelem *
     remque(struct qelem *entry)

DESCRIPTION
     insque() and remque() manipulate queues built from circular, doubly
     linked lists. Each element in the queue must begin with a "struct qelem".
     insque() inserts entry in the queue immediately after pred. remque()
     removes entry from the queue.

DIAGNOSTICS
     These functions are not atomic unless that machine architecture allows
     it.

HISTORY
     These are derived from the insque and remque instructions on a VAX.
