insque, remque -- doubly-linked list management
Standard C Library (libc, -lc)
insque(void *element1, void *pred);
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
The insque() and remque() functions appeared in 4.2BSD. In FreeBSD 5.0,
they reappeared conforming to IEEE Std 1003.1-2001 (``POSIX.1'').
