INSQUE(3)						   BSD Library Functions Manual 						 INSQUE(3)

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

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <search.h>

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

     void
     remque(void *elem);

DESCRIPTION
     insque() and remque() manipulate queues built from doubly linked lists.  The queue can be either circular or linear.  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 linear list's head element.

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

HISTORY
     The insque() and remque() are derived from the 'insque' and 'remque' instructions on the VAX.  They first appeared in 4.2BSD.
