insque
() and remque
() manipulate
queues built from doubly linked lists. The queue can be either circular or
linear. 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 linear list's head element.
insque
() and remque
()
functions conform to IEEE Std 1003.1-2001
(“POSIX.1”).
insque
() and remque
() are
derived from the ‘insque’ and ‘remque’
instructions on the VAX. They first appeared in
4.2BSD.
