#include <search.h>
void insque(void *elem, void *prev);
void remque(void *elem);
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.
POSIX 1003.1-2001
Traditionally (e.g. SunOS, Linux libc 4,5) the parameters of these functions
were of type
struct qelem *, where the struct is 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 libc4,5 placed them in <stdlib.h>.
