NAME

     insque, remque -- doubly-linked list management

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <search.h>

     void
     insque(void *element, void *pred);

     void
     remque(void *element);

DESCRIPTION

     The insque() and remque() functions encapsulate the ever-repeating task of doing insertion and removal operations on doubly linked lists.
     The functions expect their arguments to point to a structure whose first and second members are pointers to the next and previous element,
     respectively.  The insque() function also allows the pred argument to be a NULL pointer for the initialization of a new list's head element.

STANDARDS

     The insque() and remque() functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     The insque() and remque() functions appeared in 4.2BSD.  In FreeBSD 5.0, they reappeared conforming to IEEE Std 1003.1-2001 (``POSIX.1'').

NAME

       insque, remque - insert/remove element from a queue

SYNOPSIS

       include <search.h>

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

       void remque(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 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.
