NAME
insque(), remque() - insert or remove an element in a queue
SYNOPSIS
#include <search.h>
void insque(void *element, void *pred);
void remque(void *element);
DESCRIPTION
The insque() and remque() functions manipulate queues built from doubly-linked lists. An applica-
tion using these functions must define a structure in which the first two members of the structure are
pointers to the same type of structure. Any additional members of the structure are application specific.
The first two members of the structure are used for forward and backward pointers. The names of the
structure and of the pointers are not subject to any restrictions.
The insque() function inserts the object pointed to by the element argument into a queue immediately
after the object pointed to by the pred argument.
The remque() function removes the object pointed to by the element argument from a queue.
APPLICATION USAGE
insque() and remque() are thread-safe and async-cancel-safe.
AUTHOR
insque() and remque() were developed by HP and the University of California, Berkeley.
