-/** @file event2/buffer.h
-
-  Functions for buffering data for network sending or receiving.
-
-  An evbuffer can be used for preparing data before sending it to
-  the network or conversely for reading data from the network.
-  Evbuffers try to avoid memory copies as much as possible.  As a
-  result, evbuffers can be used to pass data around without actually
-  incurring the overhead of copying the data.
-
-  A new evbuffer can be allocated with evbuffer_new(), and can be
-  freed with evbuffer_free().  Most users will be using evbuffers via
-  the bufferevent interface.  To access a bufferevent's evbuffers, use
-  bufferevent_get_input() and bufferevent_get_output().
-
-  There are several guidelines for using evbuffers.
-
-  - if you already know how much data you are going to add as a result
-    of calling evbuffer_add() multiple times, it makes sense to use
-    evbuffer_expand() first to make sure that enough memory is allocated
-    before hand.
-
-  - evbuffer_add_buffer() adds the contents of one buffer to the other
-    without incurring any unnecessary memory copies.
-
-  - evbuffer_add() and evbuffer_add_buffer() do not mix very well:
-    if you use them, you will wind up with fragmented memory in your
-	buffer.
-
-  - For high-performance code, you may want to avoid copying data into and out
-    of buffers.  You can skip the copy step by using
-    evbuffer_reserve_space()/evbuffer_commit_space() when writing into a
-    buffer, and evbuffer_peek() when reading.
-
-  In Libevent 2.0 and later, evbuffers are represented using a linked
-  list of memory chunks, with pointers to the first and last chunk in
-  the chain.
-
-  As the contents of an evbuffer can be stored in multiple different
-  memory blocks, it cannot be accessed directly.  Instead, evbuffer_pullup()
-  can be used to force a specified number of bytes to be contiguous. This
-  will cause memory reallocation and memory copies if the data is split
-  across multiple blocks.  It is more efficient, however, to use
-  evbuffer_peek() if you don't require that the memory to be contiguous.

-/**
-   @file event2/bufferevent.h
-
-  Functions for buffering data for network sending or receiving.  Bufferevents
-  are higher level than evbuffers: each has an underlying evbuffer for reading
-  and one for writing, and callbacks that are invoked under certain
-  circumstances.
-
-  A bufferevent provides input and output buffers that get filled and
-  drained automatically.  The user of a bufferevent no longer deals
-  directly with the I/O, but instead is reading from input and writing
-  to output buffers.
-
-  Once initialized, the bufferevent structure can be used repeatedly
-  with bufferevent_enable() and bufferevent_disable().
-
-  When reading is enabled, the bufferevent will try to read from the
-  file descriptor onto its input buffer, and call the read callback.
-  When writing is enabled, the bufferevent will try to write data onto its
-  file descriptor when the output buffer has enough data, and call the write
-  callback when the output buffer is sufficiently drained.
-
-  Bufferevents come in several flavors, including:
-
-  <dl>
-    <dt>Socket-based bufferevents</dt>
-      <dd>A bufferevent that reads and writes data onto a network
-          socket. Created with bufferevent_socket_new().</dd>
-
-    <dt>Paired bufferevents</dt>
-      <dd>A pair of bufferevents that send and receive data to one
-          another without touching the network.  Created with
-          bufferevent_pair_new().</dd>
-
-    <dt>Filtering bufferevents</dt>
-       <dd>A bufferevent that transforms data, and sends or receives it
-          over another underlying bufferevent.  Created with
-          bufferevent_filter_new().</dd>
-
-    <dt>SSL-backed bufferevents</dt>
-      <dd>A bufferevent that uses the openssl library to send and
-          receive data over an encrypted connection. Created with
-	  bufferevent_openssl_socket_new() or
-	  bufferevent_openssl_filter_new().</dd>

-  This function is deprecated.  Use bufferevent_socket_new and

-
-  Libevent provides an abstraction on top of the regular event callbacks.
-  This abstraction is called a buffered event.  A buffered event provides
-  input and output buffers that get filled and drained automatically.  The
-  user of a buffered event no longer deals directly with the I/O, but
-  instead is reading from input and writing to output buffers.
-
-  Once initialized, the bufferevent structure can be used repeatedly with
-  bufferevent_enable() and bufferevent_disable().
-
-  When read enabled the bufferevent will try to read from the file descriptor
-  and call the read callback.  The write callback is executed whenever the
-  output buffer is drained below the write low watermark, which is 0 by
-  default.
-
-  If multiple bases are in use, bufferevent_base_set() must be called before

-
-/** @file event2/dns.h
- *
- * Welcome, gentle reader
- *
- * Async DNS lookups are really a whole lot harder than they should be,
- * mostly stemming from the fact that the libc resolver has never been
- * very good at them. Before you use this library you should see if libc
- * can do the job for you with the modern async call getaddrinfo_a
- * (see http://www.imperialviolet.org/page25.html#e498). Otherwise,
- * please continue.
- *
- * The library keeps track of the state of nameservers and will avoid
- * them when they go down. Otherwise it will round robin between them.
- *
- * Quick start guide:
- *   #include "evdns.h"
- *   void callback(int result, char type, int count, int ttl,
- *		 void *addresses, void *arg);
- *   evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf");
- *   evdns_resolve("www.hostname.com", 0, callback, NULL);
- *
- * When the lookup is complete the callback function is called. The
- * first argument will be one of the DNS_ERR_* defines in evdns.h.
- * Hopefully it will be DNS_ERR_NONE, in which case type will be
- * DNS_IPv4_A, count will be the number of IP addresses, ttl is the time
- * which the data can be cached for (in seconds), addresses will point
- * to an array of uint32_t's and arg will be whatever you passed to
- * evdns_resolve.
- *
- * Searching:
- *
- * In order for this library to be a good replacement for glibc's resolver it
- * supports searching. This involves setting a list of default domains, in
- * which names will be queried for. The number of dots in the query name
- * determines the order in which this list is used.
- *
- * Searching appears to be a single lookup from the point of view of the API,
- * although many DNS queries may be generated from a single call to
- * evdns_resolve. Searching can also drastically slow down the resolution
- * of names.
- *
- * To disable searching:
- *   1. Never set it up. If you never call evdns_resolv_conf_parse or
- *   evdns_search_add then no searching will occur.
- *
- *   2. If you do call evdns_resolv_conf_parse then don't pass
- *   DNS_OPTION_SEARCH (or DNS_OPTIONS_ALL, which implies it).
- *
- *   3. When calling evdns_resolve, pass the DNS_QUERY_NO_SEARCH flag.
- *
- * The order of searches depends on the number of dots in the name. If the
- * number is greater than the ndots setting then the names is first tried
- * globally. Otherwise each search domain is appended in turn.
- *
- * The ndots setting can either be set from a resolv.conf, or by calling
- * evdns_search_ndots_set.
- *
- * For example, with ndots set to 1 (the default) and a search domain list of
- * ["myhome.net"]:
- *  Query: www
- *  Order: www.myhome.net, www.
- *
- *  Query: www.abc
- *  Order: www.abc., www.abc.myhome.net
- *
- * Internals:
- *
- * Requests are kept in two queues. The first is the inflight queue. In
- * this queue requests have an allocated transaction id and nameserver.
- * They will soon be transmitted if they haven't already been.
- *
- * The second is the waiting queue. The size of the inflight ring is
- * limited and all other requests wait in waiting queue for space. This
- * bounds the number of concurrent requests so that we don't flood the
- * nameserver. Several algorithms require a full walk of the inflight
- * queue and so bounding its size keeps thing going nicely under huge
- * (many thousands of requests) loads.
- *
- * If a nameserver loses too many requests it is considered down and we
- * try not to use it. After a while we send a probe to that nameserver
- * (a lookup for google.com) and, if it replies, we consider it working
- * again. If the nameserver fails a probe we wait longer to try again
- * with the next probe.

-   @mainpage
-
-  @section intro Introduction
-
-  Libevent is an event notification library for developing scalable network
-  servers.  The Libevent API provides a mechanism to execute a callback
-  function when a specific event occurs on a file descriptor or after a
-  timeout has been reached. Furthermore, Libevent also support callbacks due
-  to signals or regular timeouts.
-
-  Libevent is meant to replace the event loop found in event driven network
-  servers. An application just needs to call event_base_dispatch() and then add or
-  remove events dynamically without having to change the event loop.
-
-
-  Currently, Libevent supports /dev/poll, kqueue(2), select(2), poll(2),
-  epoll(4), and evports. The internal event mechanism is completely
-  independent of the exposed event API, and a simple update of Libevent can
-  provide new functionality without having to redesign the applications. As a
-  result, Libevent allows for portable application development and provides
-  the most scalable event notification mechanism available on an operating
-  system.  Libevent can also be used for multithreaded programs.  Libevent
-  should compile on Linux, *BSD, Mac OS X, Solaris and, Windows.
-
-  @section usage Standard usage
-
-  Every program that uses Libevent must include the <event2/event.h>
-  header, and pass the -levent flag to the linker.  (You can instead link
-  -levent_core if you only want the main event and buffered IO-based code,
-  and don't want to link any protocol code.)
-
-  @section setup Library setup
-
-  Before you call any other Libevent functions, you need to set up the
-  library.  If you're going to use Libevent from multiple threads in a
-  multithreaded application, you need to initialize thread support --
-  typically by using evthread_use_pthreads() or
-  evthread_use_windows_threads().  See <event2/thread.h> for more
-  information.
-
-  This is also the point where you can replace Libevent's memory
-  management functions with event_set_mem_functions, and enable debug mode
-  with event_enable_debug_mode().
-
-  @section base Creating an event base
-
-  Next, you need to create an event_base structure, using event_base_new()
-  or event_base_new_with_config().  The event_base is responsible for
-  keeping track of which events are "pending" (that is to say, being
-  watched to see if they become active) and which events are "active".
-  Every event is associated with a single event_base.
-
-  @section event Event notification
-
-  For each file descriptor that you wish to monitor, you must create an
-  event structure with event_new().  (You may also declare an event
-  structure and call event_assign() to initialize the members of the
-  structure.)  To enable notification, you add the structure to the list
-  of monitored events by calling event_add().  The event structure must
-  remain allocated as long as it is active, so it should generally be
-  allocated on the heap.
-
-  @section loop Dispatching events.
-
-  Finally, you call event_base_dispatch() to loop and dispatch events.
-  You can also use event_base_loop() for more fine-grained control.
-
-  Currently, only one thread can be dispatching a given event_base at a
-  time.  If you want to run events in multiple threads at once, you can
-  either have a single event_base whose events add work to a work queue,
-  or you can create multiple event_base objects.
-
-  @section bufferevent I/O Buffers
-
-  Libevent provides a buffered I/O abstraction on top of the regular event
-  callbacks. This abstraction is called a bufferevent. A bufferevent
-  provides input and output buffers that get filled and drained
-  automatically. The user of a buffered event no longer deals directly
-  with the I/O, but instead is reading from input and writing to output
-  buffers.
-
-  Once initialized via bufferevent_socket_new(), the bufferevent structure
-  can be used repeatedly with bufferevent_enable() and
-  bufferevent_disable().  Instead of reading and writing directly to a
-  socket, you would call bufferevent_read() and bufferevent_write().
-
-  When read enabled the bufferevent will try to read from the file descriptor
-  and call the read callback. The write callback is executed whenever the
-  output buffer is drained below the write low watermark, which is 0 by
-  default.
-
-  See <event2/bufferevent*.h> for more information.
-
-  @section timers Timers
-
-  Libevent can also be used to create timers that invoke a callback after a
-  certain amount of time has expired. The evtimer_new() macro returns
-  an event struct to use as a timer. To activate the timer, call
-  evtimer_add(). Timers can be deactivated by calling evtimer_del().
-  (These macros are thin wrappers around event_new(), event_add(),
-  and event_del(); you can also use those instead.)
-
-  @section evdns Asynchronous DNS resolution
-
-  Libevent provides an asynchronous DNS resolver that should be used instead
-  of the standard DNS resolver functions.  See the <event2/dns.h>
-  functions for more detail.
-
-  @section evhttp Event-driven HTTP servers
-
-  Libevent provides a very simple event-driven HTTP server that can be
-  embedded in your program and used to service HTTP requests.
-
-  To use this capability, you need to include the <event2/http.h> header in your
-  program.  See that header for more information.
-
-  @section evrpc A framework for RPC servers and clients
-
-  Libevent provides a framework for creating RPC servers and clients.  It
-  takes care of marshaling and unmarshaling all data structures.
-
-  @section api API Reference

- * @struct event
- *
- * Structure to represent a single event.
- *
- * An event can have some underlying condition it represents: a socket
- * becoming readable or writeable (or both), or a signal becoming raised.
- * (An event that represents no underlying condition is still useful: you
- * can use one to implement a timer, or to communicate between threads.)
- *
- * Generally, you can create events with event_new(), then make them
- * pending with event_add().  As your event_base runs, it will run the
- * callbacks of an events whose conditions are triggered.  When you
- * longer want the event, free it with event_free().
- *
- * In more depth:
- *
- * An event may be "pending" (one whose condition we are watching),
- * "active" (one whose condition has triggered and whose callback is about
- * to run), neither, or both.  Events come into existence via
- * event_assign() or event_new(), and are then neither active nor pending.
- *
- * To make an event pending, pass it to event_add().  When doing so, you
- * can also set a timeout for the event.
- *
- * Events become active during an event_base_loop() call when either their
- * condition has triggered, or when their timeout has elapsed.  You can
- * also activate an event manually using event_active().  The even_base
- * loop will run the callbacks of active events; after it has done so, it
- * marks them as no longer active.
- *
- * You can make an event non-pending by passing it to event_del().  This
- * also makes the event non-active.
- *
- * Events can be "persistent" or "non-persistent".  A non-persistent event
- * becomes non-pending as soon as it is triggered: thus, it only runs at
- * most once per call to event_add().  A persistent event remains pending
- * even when it becomes active: you'll need to event_del() it manually in
- * order to make it non-pending.  When a persistent event with a timeout
- * becomes active, its timeout is reset: this means you can use persistent
- * events to implement periodic timeouts.
- *
- * This should be treated as an opaque structure; you should never read or
- * write any of its fields directly.  For backward compatibility with old
- * code, it is defined in the event2/event_struct.h header; including this
- * header may make your code incompatible with other versions of Libevent.
