INSQUE(3) Library Functions Manual INSQUE(3) NAME insque, remque - insert/remove element from a queue LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <search.h> void insque(void *elem, void *pred); void remque(void *elem); DESCRIPTION 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. STANDARDS The insque() and remque() functions conform to IEEE Std 1003.1-2001 ("POSIX.1"). HISTORY The insque() and remque() are derived from the `insque' and `remque' instructions on the VAX. They first appeared in 4.2BSD. NetBSD 8.99.34 April 30, 2010 NetBSD 8.99.34
