insque, remque
— doubly-linked list management
Standard C Library (libc, -lc)
#include
<search.h>
void
insque(void
*element, void
*pred);
void
remque(void
*element);
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.
The insque() and
remque() functions conform to IEEE
Std 1003.1-2001 (“POSIX.1”).
The insque() and
remque() functions appeared in
4.2BSD. In FreeBSD 5.0, they
reappeared conforming to IEEE Std 1003.1-2001
(“POSIX.1”).
