Name
       insque, remque - insert/remove element from a queue

Syntax
       struct qelem {
       struct	 qelem *q_forw;
       struct	 qelem *q_back;
       char q_data[];
       };

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

       void remque(elem)
       struct qelem *elem;

Description
       The and subroutines manipulate queues built from doubly linked lists.  Each element in the queue must in the form of ``struct qelem.''  The
       subroutine inserts elem in a queue immediately after pred.  The subroutine removes an entry elem from a queue.

NAME
insque, remque - insert/remove an item from a queue SYNOPSIS
#include <search.h> void insque(void *elem, void *prev); void remque(void *elem); Feature Test Macro Requirements for glibc (see feature_test_macros(7)): insque(), remque(): _SVID_SOURCE || _XOPEN_SOURCE >= 500 DESCRIPTION
insque() and remque() are functions for manipulating doubly-linked lists. Each element in the list is a structure of which the first two structure elements are a forward and a backward pointer. insque() inserts the element pointed to by elem immediately after the element pointed to by prev, which must not be NULL. remque() removes the element pointed to by elem from the doubly-linked list. CONFORMING TO
POSIX.1-2001. NOTES
Traditionally (e.g., SunOS, Linux libc 4 and libc 5), the arguments of these functions were of type struct qelem *, defined as: struct qelem { struct qelem *q_forw; struct qelem *q_back; char q_data[1]; }; This is still what you will get if _GNU_SOURCE is defined before including <search.h>. The location of the prototypes for these functions differs among several versions of Unix. The above is the POSIX version. Some systems place them in <string.h>. Linux libc4 and libc 5 placed them in <stdlib.h>. COLOPHON
