INSQUE(3)						     Linux Programmer's Manual							 INSQUE(3)

NAME

       insque, remque - insert/remove an item from a queue

SYNOPSIS

       #include <stdlib.h>

       void insque(struct qelem *elem, struct qelem *prev);
       void remque(struct qelem *elem);

DESCRIPTION

       insque()  and  remque()	are  functions for manipulating queues made from doubly-linked lists.  Each element in this list is of type struct
       qelem

       The qelem structure is defined as

	      struct qelem {
		  struct    qelem *q_forw;
		  struct    qelem *q_back;
		  char	    q_data[1];
	      };

       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.

BUGS

       The q_data field is sometimes defined to be type char *, and under solaris 2.x, it doesn't appear to exist at all.

       The location of the prototypes for these functions differ among several versions of UNIX.  Some systems place them in <search.h>, others in
       <string.h>.  Linux places them in <stdlib.h> since that seems to make the most sense.

       Some versions of UNIX (like HP-UX 10.x) do not define a struct qelem but rather have the arguments to insque() and remque() be of type void
       *.

NAME

       insque, remque - insert/remove element from a queue

SYNOPSIS

       include <search.h>

       void insque(struct qelem *elem, struct qelem *pred);

       void remque(struct qelem *elem);

DESCRIPTION

       The  insque()  and remque() functions manipulate queues built from doubly linked lists.	Each element in the queue must be in the following
       form:

	 struct qelem {
		 struct qelem	*q_forw;
		 struct qelem	*q_back;
		 char		q_data[];
	 };

       The insque() function inserts elem in a queue immediately after pred.  The remque() function removes an entry elem from a queue.
