INSQUE(3) FreeBSD 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 *element1, 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").
