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

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'').
