+/*
+ * This file defines five types of data structures: singly-linked lists, 
+ * lists, simple queues, tail queues, and circular queues.
+ *
+ *
+ * A singly-linked list is headed by a single forward pointer. The elements
+ * are singly linked for minimum space and pointer manipulation overhead at
+ * the expense of O(n) removal for arbitrary elements. New elements can be
+ * added to the list after an existing element or at the head of the list.
+ * Elements being removed from the head of the list should use the explicit
+ * macro for this purpose for optimum efficiency. A singly-linked list may
+ * only be traversed in the forward direction.  Singly-linked lists are ideal
+ * for applications with large datasets and few or no removals or for
+ * implementing a LIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may only be traversed in the forward direction.
+ *
+ * A simple queue is headed by a pair of pointers, one the head of the
+ * list and the other to the tail of the list. The elements are singly
+ * linked to save space, so elements can only be removed from the
+ * head of the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the
+ * list. A simple queue may only be traversed in the forward direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * A circle queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the list.
+ * A circle queue may be traversed in either direction, but has a more
+ * complex end of list detection.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.

+ * This file defines data structures for different types of trees:
+ * splay trees and red-black trees.
+ *
+ * A splay tree is a self-organizing data structure.  Every operation
+ * on the tree causes a splay to happen.  The splay moves the requested
+ * node to the root of the tree and partly rebalances it.
+ *
+ * This has the benefit that request locality causes faster lookups as
+ * the requested nodes move to the top of the tree.  On the other hand,
+ * every lookup causes memory writes.
+ *
+ * The Balance Theorem bounds the total access time for m operations
+ * and n inserts on an initially empty tree as O((m + n)lg n).  The
+ * amortized cost for a sequence of m accesses to a splay tree is O(lg n);
+ *
+ * A red-black tree is a binary search tree with the node color as an
+ * extra attribute.  It fulfills a set of conditions:
+ *	- every search path from the root to a leaf consists of the
+ *	  same number of black nodes,
+ *	- each red node (except for the root) has a black parent,
+ *	- each leaf node is black.
+ *
+ * Every operation on a red-black tree is bounded as O(lg n).
+ * The maximum height of a red-black tree is 2lg (n+1).

+.Sh DESCRIPTION
+The
+.Nm event
+API provides a mechanism to execute a function when a specific event
+on a file descriptor occurs or after at a given time has passed.
+.Pp
+The
+.Nm event
+API needs to be initalized with
+.Fn event_init
+before it can be used.
+.Pp
+In order to process events, an application needs to call
+.Fn event_dispatch .
+This functions only returns on error, and should replace the event core
+of the application program.
+.Pp
+In order to avoid races in signal handlers, the
+.Nm event
+API provides two variables:
+.Va event_sigcb
+and
+.Va event_gotsig .
+A signal handler
+sets
+.Va event_gotsig
+to indicate that a signal has been received.
+The application sets
+.Va event_sigcb
+to a callback function.  After the signal handler sets
+.Va event_gotsig ,
+.Nm event_dispatch
+will execute the callback function to process received signals.  The
+callback returns 1 when no events are registered any more.  It can
+return -1 to indicate an error to the
+.Nm event
+library, causing
+.Fn event_dispatch
+to terminate with
+.Va errno
+set to
+.Er EINTR.
+.Pp
+The
+.Nm event_loop
+function provides an interface for single pass execution of pending
+events.  The flags
+.Va EVLOOP_ONCE
+and
+.Va EVLOOP_NONBLOCK
+are recognized.
+.Pp
+It is the responsibility of the caller to provide these functions with
+pre-allocated event structures.
+.Pp
+The function
+.Fn event_set
+prepares the event structure
+.Fa ev
+to be used in future calls to
+.Fn event_add
+and
+.Fn event_del .
+The event will be prepared to call the function specified by the
+.Fa fn
+argument with an
+.Fa int
+argument indicating the file descriptor, with a
+.Fa short
+argument indicating the type of event, and a
+.Fa void *
+argument given in the
+.Fa arg
+argument.
+The 
+.Fa fd
+indicates the file descriptor that should be monitored for events.
+The events can be either
+.Va EV_READ,
+.Va EV_WRITE,
+or both.
+Indicating that an application can read or write from the file descriptor
+respectively without blocking.
+.Pp
+The function
+.Fa fn
+will be called with the file descriptor that triggered the event and
+the type of event which will be either
+.Va EV_TIMEOUT ,
+.Va EV_SIGNAL ,
+.Va EV_READ ,
+or
+.Va EV_WRITE .
+The additional flag
+.Va EV_PERSIST
+makes an
+.Fn event_add
+persistent until
+.Fn event_del
+has been called.
+.Pp
+Once initialized, the
+.Fa ev
+structure can be used repeatedly with
+.Fn event_add
+and
+.Fn event_del
+and does not need to be reinitialized unless you wish to
+change the function called and/or the argument to it.
+.Pp
+The function
+.Fn event_add
+schedules the execution of the
+.Fa ev
+event when the event specified in 
+.Fn event_set
+occurs or in at least the time specified in the
+.Fa tv .
+If
+.Fa tv
+is NULL, no timeout occurs and the function will only be called
+if a matching event occurs on the file descriptor.
+The event in the
+.Fa ev
+argument must be already initialized by
+.Fn event_set
+and may not be used in calls to
+.Fn event_set
+until it has timed out or been removed with
+.Fn event_del .
+If the event in the
+.Fa ev
+argument has already a scheduled timeout, the old timeout will be
+replaced by the new one.
+.Pp
+The function
+.Fn event_del
+will cancel the event in the argument
+.Fa ev .
+If the event has already executed or has never been added
+the call will have no effect.
+.Pp
+The
+.Fn event_pending
+function can be used to check if the event specified by
+.Fa event
+is pending to run.
+If
+.Va EV_TIMEOUT
+was specified and 
+.Fa tv
+is not
+.Va NULL ,
+the expiration time of the event will be returned in
+.Fa tv .
+.Pp
+The
+.Fn event_initialized
+macro can be used to check if an event has been initialized.
+.Pp
+The functions
+.Fn timeout_set ,
+.Fn timeout_add ,
+.Fn timeout_del ,
+.Fn timeout_initialized ,
+and
+.Fn timeout_pending
+are abbreviations for common situations where only a timeout is required.
+The file descriptor passed will be 0, and the event type will be
+.Va EV_TIMEOUT .
+.Pp
+.Pp
+The functions
+.Fn signal_set ,
+.Fn signal_add ,
+.Fn signal_del ,
+.Fn signal_initialized ,
+and
+.Fn signal_pending
+are abbreviations.
+The event type will be a persistent
+.Va EV_SIGNAL .
+That means
+.Fn signal_set
+adds
+.Va EV_PERSIST .
+.Pp
+It is possible to disable support for
+.Va kqueue
+by setting the environment variable
+.Va EVENT_NOKQUEUE .
+.Pp
+.Sh RETURN VALUES
+Upon successful completion
+.Fn event_add
+and
+.Fn event_del
+return 0.
+Otherwise, -1 is returned and the global variable errno is
+set to indicate the error.
