ENet 1.3.17 (November 15, 2020):
* fixes for sender getting too far ahead of receiver that can cause instability with reliable packets
ENet 1.3.16 (September 8, 2020):
* fix bug in unreliable fragment queuing
* use single output queue for reliable and unreliable packets for saner ordering
* revert experimental throttle changes that were less stable than prior algorithm
ENet 1.3.15 (April 20, 2020):
* quicker RTT initialization
* use fractional precision for RTT calculations
* fixes for packet throttle with low RTT variance
* miscellaneous socket bug fixes
ENet 1.3.14 (January 27, 2019):
* bug fix for enet_peer_disconnect_later()
* use getaddrinfo and getnameinfo where available
* miscellaneous cleanups
ENet 1.3.13 (April 30, 2015):
* miscellaneous bug fixes
* added premake and cmake support
* miscellaneous documentation cleanups
ENet 1.3.12 (April 24, 2014):
* added maximumPacketSize and maximumWaitingData fields to ENetHost to limit the amount of
data waiting to be delivered on a peer (beware that the default maximumPacketSize is
32MB and should be set higher if desired as should maximumWaitingData)
ENet 1.3.11 (December 26, 2013):
* allow an ENetHost to connect to itself
* fixed possible bug with disconnect notifications during connect attempts
* fixed some preprocessor definition bugs
ENet 1.3.10 (October 23, 2013);
* doubled maximum reliable window size
* fixed RCVTIMEO/SNDTIMEO socket options and also added NODELAY
ENet 1.3.9 (August 19, 2013):
* added duplicatePeers option to ENetHost which can limit the number of peers from duplicate IPs
* added enet_socket_get_option() and ENET_SOCKOPT_ERROR
* added enet_host_random_seed() platform stub
ENet 1.3.8 (June 2, 2013):
* added enet_linked_version() for checking the linked version
* added enet_socket_get_address() for querying the local address of a socket
* silenced some debugging prints unless ENET_DEBUG is defined during compilation
* handle EINTR in enet_socket_wait() so that enet_host_service() doesn't propagate errors from signals
* optimized enet_host_bandwidth_throttle() to be less expensive for large numbers of peers
ENet 1.3.7 (March 6, 2013):
* added ENET_PACKET_FLAG_SENT to indicate that a packet is being freed because it has been sent
* added userData field to ENetPacket
* changed how random seed is generated on Windows to avoid import warnings
* fixed case where disconnects could be generated with no preceding connect event
ENet 1.3.6 (December 11, 2012):
* added support for intercept callback in ENetHost that can be used to process raw packets before ENet
* added enet_socket_shutdown() for issuing shutdown on a socket
* fixed enet_socket_connect() to not error on non-blocking connects
* fixed bug in MTU negotiation during connections
ENet 1.3.5 (July 31, 2012):
* fixed bug in unreliable packet fragment queuing
ENet 1.3.4 (May 29, 2012):
* added enet_peer_ping_interval() for configuring per-peer ping intervals
* added enet_peer_timeout() for configuring per-peer timeouts
* added protocol packet size limits
ENet 1.3.3 (June 28, 2011):
* fixed bug with simultaneous disconnects not dispatching events
ENet 1.3.2 (May 31, 2011):
* added support for unreliable packet fragmenting via the packet flag
ENET_PACKET_FLAG_UNRELIABLE_FRAGMENT
* fixed regression in unreliable packet queuing
* added check against received port to limit some forms of IP-spoofing
ENet 1.3.1 (February 10, 2011):
* fixed bug in tracking of reliable data in transit
* reliable data window size now scales with the throttle
* fixed bug in fragment length calculation when checksums are used
ENet 1.3.0 (June 5, 2010):
* enet_host_create() now requires the channel limit to be specified as
a parameter
* enet_host_connect() now accepts a data parameter which is supplied
to the receiving receiving host in the event data field for a connect event
* added an adaptive order-2 PPM range coder as a built-in compressor option
which can be set with enet_host_compress_with_range_coder()
* added support for packet compression configurable with a callback
* improved session number handling to not rely on the packet checksum
field, saving 4 bytes per packet unless the checksum option is used
* removed the dependence on the rand callback for session number handling
Caveats: This version is not protocol compatible with the 1.2 series or
earlier. The enet_host_connect and enet_host_create API functions require
supplying additional parameters.
ENet 1.2.5 (June 28, 2011):
* fixed bug with simultaneous disconnects not dispatching events
ENet 1.2.4 (May 31, 2011):
* fixed regression in unreliable packet queuing
* added check against received port to limit some forms of IP-spoofing
ENet 1.2.3 (February 10, 2011):
* fixed bug in tracking reliable data in transit
ENet 1.2.2 (June 5, 2010):
* checksum functionality is now enabled by setting a checksum callback
inside ENetHost instead of being a configure script option
* added totalSentData, totalSentPackets, totalReceivedData, and
totalReceivedPackets counters inside ENetHost for getting usage
statistics
* added enet_host_channel_limit() for limiting the maximum number of
channels allowed by connected peers
* now uses dispatch queues for event dispatch rather than potentially
unscalable array walking
* added no_memory callback that is called when a malloc attempt fails,
such that if no_memory returns rather than aborts (the default behavior),
then the error is propagated to the return value of the API calls
* now uses packed attribute for protocol structures on platforms with
strange alignment rules
* improved autoconf build system contributed by Nathan Brink allowing
for easier building as a shared library
Caveats: If you were using the compile-time option that enabled checksums,
make sure to set the checksum callback inside ENetHost to enet_crc32 to
regain the old behavior. The ENetCallbacks structure has added new fields,
so make sure to clear the structure to zero before use if
using enet_initialize_with_callbacks().
ENet 1.2.1 (November 12, 2009):
* fixed bug that could cause disconnect events to be dropped
* added thin wrapper around select() for portable usage
* added ENET_SOCKOPT_REUSEADDR socket option
* factored enet_socket_bind()/enet_socket_listen() out of enet_socket_create()
* added contributed Code::Blocks build file
ENet 1.2 (February 12, 2008):
* fixed bug in VERIFY_CONNECT acknowledgement that could cause connect
attempts to occasionally timeout
* fixed acknowledgements to check both the outgoing and sent queues
when removing acknowledged packets
* fixed accidental bit rot in the MSVC project file
* revised sequence number overflow handling to address some possible
disconnect bugs
* added enet_host_check_events() for getting only local queued events
* factored out socket option setting into enet_socket_set_option() so
that socket options are now set separately from enet_socket_create()
Caveats: While this release is superficially protocol compatible with 1.1,
differences in the sequence number overflow handling can potentially cause
random disconnects.
ENet 1.1 (June 6, 2007):
* optional CRC32 just in case someone needs a stronger checksum than UDP
provides (--enable-crc32 configure option)
* the size of packet headers are half the size they used to be (so less
overhead when sending small packets)
* enet_peer_disconnect_later() that waits till all queued outgoing
packets get sent before issuing an actual disconnect
* freeCallback field in individual packets for notification of when a
packet is about to be freed
* ENET_PACKET_FLAG_NO_ALLOCATE for supplying pre-allocated data to a
packet (can be used in concert with freeCallback to support some custom
allocation schemes that the normal memory allocation callbacks would
normally not allow)
* enet_address_get_host_ip() for printing address numbers
* promoted the enet_socket_*() functions to be part of the API now
* a few stability/crash fixes

/**
@page FAQ Frequently Answered Questions
@section Q1 Is ENet thread-safe?
ENet does not use any significant global variables, the vast majority
of state is encapsulated in the ENetHost structure. As such, as long
as the application guards access to this structure, then ENet should
operate fine in a multi-threaded environment.
@section Q2 Isn't ENet just re-inventing TCP?! What's the point?
In a perfect world, that would be true. But as many have found, using
TCP either in lieu of or in conjunction with UDP can lead to all kinds
of nightmares. TCP is a good, solid protocol, however it simply isn't
up to the task of real-time games. Too much of TCP's implementation
dictates a policy that isn't practical for games. If you want to use
TCP, then do so -- this library is for people that either don't want
to use TCP or have tried and ended up being discouraged with the
performance.

/**
@page Features Features and Architecture
ENet evolved specifically as a UDP networking layer for the
multiplayer first person shooter Cube. Cube necessitated low latency
communication with data sent out very frequently, so TCP was an
unsuitable choice due to its high latency and stream orientation. UDP,
however, lacks many sometimes necessary features from TCP such as
reliability, sequencing, unrestricted packet sizes, and connection
management. So UDP by itself was not suitable as a network protocol
either. No suitable freely available networking libraries existed at
the time of ENet's creation to fill this niche.
UDP and TCP could have been used together in Cube to benefit somewhat
from both of their features, however, the resulting combinations of
protocols still leaves much to be desired. TCP lacks multiple streams
of communication without resorting to opening many sockets and
complicates delineation of packets due to its buffering behavior. UDP
lacks sequencing, connection management, management of bandwidth
resources, and imposes limitations on the size of packets. A
significant investment is required to integrate these two protocols,
and the end result is worse off in features and performance than the
uniform protocol presented by ENet.
ENet thus attempts to address these issues and provide a single,
uniform protocol layered over UDP to the developer with the best
features of UDP and TCP as well as some useful features neither
provide, with a much cleaner integration than any resulting from a
mixture of UDP and TCP.
@section CM Connection Management
ENet provides a simple connection interface over which to communicate
with a foreign host. The liveness of the connection is actively
monitored by pinging the foreign host at frequent intervals, and also
monitors the network conditions from the local host to the foreign
host such as the mean round trip time and packet loss in this fashion.
@section Sequencing Sequencing
Rather than a single byte stream that complicates the delineation of
packets, ENet presents connections as multiple, properly sequenced
packet streams that simplify the transfer of various types of data.
ENet provides sequencing for all packets by assigning to each sent
packet a sequence number that is incremented as packets are sent. ENet
guarantees that no packet with a higher sequence number will be
delivered before a packet with a lower sequence number, thus ensuring
packets are delivered exactly in the order they are sent.
For unreliable packets, ENet will simply discard the lower sequence
number packet if a packet with a higher sequence number has already
been delivered. This allows the packets to be dispatched immediately
as they arrive, and reduce latency of unreliable packets to an
absolute minimum. For reliable packets, if a higher sequence number
packet arrives, but the preceding packets in the sequence have not yet
arrived, ENet will stall delivery of the higher sequence number
packets until its predecessors have arrived.
@section Channels Channels
Since ENet will stall delivery of reliable packets to ensure proper
sequencing, and consequently any packets of higher sequence number
whether reliable or unreliable, in the event the reliable packet's
predecessors have not yet arrived, this can introduce latency into the
delivery of other packets which may not need to be as strictly ordered
with respect to the packet that stalled their delivery.
To combat this latency and reduce the ordering restrictions on
packets, ENet provides multiple channels of communication over a given
connection. Each channel is independently sequenced, and so the
delivery status of a packet in one channel will not stall the delivery
of other packets in another channel.
@section Reliability Reliability
ENet provides optional reliability of packet delivery by ensuring the
foreign host acknowledges receipt of all reliable packets. ENet will
attempt to resend the packet up to a reasonable amount of times, if no
acknowledgement of the packet's receipt happens within a specified
timeout. Retry timeouts are progressive and become more lenient with
every failed attempt to allow for temporary turbulence in network
conditions.
@section FaR Fragmentation and Reassembly
ENet will send and deliver packets regardless of size. Large packets
are fragmented into many smaller packets of suitable size, and
reassembled on the foreign host to recover the original packet for
delivery. The process is entirely transparent to the developer.
@section Aggregation Aggregation
ENet aggregates all protocol commands, including acknowledgements and
packet transfer, into larger protocol packets to ensure the proper
utilization of the connection and to limit the opportunities for
packet loss that might otherwise result in further delivery latency.
@section Adaptability Adaptability
ENet provides an in-flight data window for reliable packets to ensure
connections are not overwhelmed by volumes of packets. It also
provides a static bandwidth allocation mechanism to ensure the total
volume of packets sent and received to a host don't exceed the host's
capabilities. Further, ENet also provides a dynamic throttle that
responds to deviations from normal network connections to rectify
various types of network congestion by further limiting the volume of
packets sent.
@section Portability Portability
ENet works on Windows and any other Unix or Unix-like platform
providing a BSD sockets interface. The library has a small and stable
code base that can easily be extended to support other platforms and
integrates easily. ENet makes no assumptions about the underlying
platform's endianess or word size.
@section Freedom Freedom
ENet demands no royalties and doesn't carry a viral license that would
restrict you in how you might use it in your programs. ENet is
licensed under a short-and-sweet MIT-style license, which gives you
the freedom to do anything you want with it (well, almost anything).

/**
@page Installation Installation
ENet should be trivially simple to integrate with most applications.
First, make sure you download the latest source distribution at @ref Downloads.
@section Unix Unix-like Operating Systems
If you are using an ENet release, then you should simply be able to build it
by doing the following:
./configure && make && make install
If you obtained the package from github, you must have automake and autoconf
available to generate the build system first by doing the following command
before using the above mentioned build procedure:
autoreconf -vfi
@subsection SolarisBSD Solaris and BSD
When building ENet under Solaris, you must specify the -lsocket and
-lnsl parameters to your compiler to ensure that the sockets library
is linked in.
@section Windows Microsoft Windows
You may simply use the included "enet.lib" or "enet64.lib" static libraries.
However, if you wish to build the library yourself, then the following
instructions apply:
There is an included MSVC 6 project (enet.dsp) which you may use to
build a suitable library file. Alternatively, you may simply drag all
the ENet source files into your main project.
You will have to link to the Winsock2 libraries, so make sure to add
ws2_32.lib and winmm.lib to your library list (Project Settings | Link |
Object/library modules).
@subsection enet.dsp Building with the included enet.dsp
Load the included enet.dsp. MSVC may ask you to convert it if you
are on a newer version of MSVC - just allow the conversion and save
the resulting project as "enet" or similar. After you build this
project, it will output an "enet.lib" file to either the "Debug/"
or "Release/" directory, depending on which configuration you have
selected to build. By default, it should produce "Debug/enet.lib".
You may then copy the resulting "enet.lib" file and the header files
found in the "include/" directory to your other projects and add it to
their library lists. Make sure to also link against "ws2_32.lib" and
"winmm.lib" as described above.
@subsection DLL DLL
If you wish to build ENet as a DLL you must first define ENET_DLL
within the project (Project Settings | C/C++ | Preprocessor |
Preprocessor definitions) or, more invasively, simply define ENET_DLL
at the top of enet.h.

@section Initialization Initialization
You should include the file <enet/enet.h> when using ENet. Do not
include <enet.h> without the directory prefix, as this may cause
file name conflicts on some systems.
Before using ENet, you must call enet_initialize() to initialize the
library. Upon program exit, you should call enet_deinitialize() so
that the library may clean up any used resources.
@code
#include <enet/enet.h>
int
main (int argc, char ** argv)
{
if (enet_initialize () != 0)
{
fprintf (stderr, "An error occurred while initializing ENet.\n");
return EXIT_FAILURE;
}
atexit (enet_deinitialize);
...
...
...
}
@endcode
@section CreateServer Creating an ENet server
Servers in ENet are constructed with enet_host_create(). You must
specify an address on which to receive data and new connections, as
well as the maximum allowable numbers of connected peers. You may
optionally specify the incoming and outgoing bandwidth of the server
in bytes per second so that ENet may try to statically manage
bandwidth resources among connected peers in addition to its dynamic
throttling algorithm; specifying 0 for these two options will cause
ENet to rely entirely upon its dynamic throttling algorithm to manage
bandwidth.
When done with a host, the host may be destroyed with
enet_host_destroy(). All connected peers to the host will be reset,
and the resources used by the host will be freed.
@code
ENetAddress address;
ENetHost * server;
/* Bind the server to the default localhost. */
/* A specific host address can be specified by */
/* enet_address_set_host (& address, "x.x.x.x"); */
address.host = ENET_HOST_ANY;
/* Bind the server to port 1234. */
address.port = 1234;
server = enet_host_create (& address /* the address to bind the server host to */,
32 /* allow up to 32 clients and/or outgoing connections */,
2 /* allow up to 2 channels to be used, 0 and 1 */,
0 /* assume any amount of incoming bandwidth */,
0 /* assume any amount of outgoing bandwidth */);
if (server == NULL)
{
fprintf (stderr,
"An error occurred while trying to create an ENet server host.\n");
exit (EXIT_FAILURE);
}
...
...
...
enet_host_destroy(server);
@endcode
@section CreateClient Creating an ENet client
Clients in ENet are similarly constructed with enet_host_create() when
no address is specified to bind the host to. Bandwidth may be
specified for the client host as in the above example. The peer count
controls the maximum number of connections to other server hosts that
may be simultaneously open.
@code
ENetHost * client;
client = enet_host_create (NULL /* create a client host */,
1 /* only allow 1 outgoing connection */,
2 /* allow up 2 channels to be used, 0 and 1 */,
0 /* assume any amount of incoming bandwidth */,
0 /* assume any amount of outgoing bandwidth */);
if (client == NULL)
{
fprintf (stderr,
"An error occurred while trying to create an ENet client host.\n");
exit (EXIT_FAILURE);
}
...
...
...
enet_host_destroy(client);
@endcode
@section ManageHost Managing an ENet host
ENet uses a polled event model to notify the programmer of significant
events. ENet hosts are polled for events with enet_host_service(),
where an optional timeout value in milliseconds may be specified to
control how long ENet will poll; if a timeout of 0 is specified,
enet_host_service() will return immediately if there are no events to
dispatch. enet_host_service() will return 1 if an event was dispatched
within the specified timeout.
Beware that most processing of the network with the ENet stack is done
inside enet_host_service(). Both hosts that make up the sides of a connection
must regularly call this function to ensure packets are actually sent and
received. A common symptom of not actively calling enet_host_service()
on both ends is that one side receives events while the other does not.
The best way to schedule this activity to ensure adequate service is, for
example, to call enet_host_service() with a 0 timeout (meaning non-blocking)
at the beginning of every frame in a game loop.
Currently there are only four types of significant events in ENet:
An event of type ENET_EVENT_TYPE_NONE is returned if no event occurred
within the specified time limit. enet_host_service() will return 0
with this event.
An event of type ENET_EVENT_TYPE_CONNECT is returned when either a new client
host has connected to the server host or when an attempt to establish a
connection with a foreign host has succeeded. Only the "peer" field of the
event structure is valid for this event and contains the newly connected peer.
An event of type ENET_EVENT_TYPE_RECEIVE is returned when a packet is received
from a connected peer. The "peer" field contains the peer the packet was
received from, "channelID" is the channel on which the packet was sent, and
"packet" is the packet that was sent. The packet contained in the "packet"
field must be destroyed with enet_packet_destroy() when you are done
inspecting its contents.
An event of type ENET_EVENT_TYPE_DISCONNECT is returned when a connected peer
has either explicitly disconnected or timed out. Only the "peer" field of the
event structure is valid for this event and contains the peer that
disconnected. Only the "data" field of the peer is still valid on a
disconnect event and must be explicitly reset.
@code
ENetEvent event;
/* Wait up to 1000 milliseconds for an event. */
while (enet_host_service (client, & event, 1000) > 0)
{
switch (event.type)
{
case ENET_EVENT_TYPE_CONNECT:
printf ("A new client connected from %x:%u.\n",
event.peer -> address.host,
event.peer -> address.port);
/* Store any relevant client information here. */
event.peer -> data = "Client information";
break;
case ENET_EVENT_TYPE_RECEIVE:
printf ("A packet of length %u containing %s was received from %s on channel %u.\n",
event.packet -> dataLength,
event.packet -> data,
event.peer -> data,
event.channelID);
/* Clean up the packet now that we're done using it. */
enet_packet_destroy (event.packet);
break;
case ENET_EVENT_TYPE_DISCONNECT:
printf ("%s disconnected.\n", event.peer -> data);
/* Reset the peer's client information. */
event.peer -> data = NULL;
}
}
...
...
...
@endcode
@section SendingPacket Sending a packet to an ENet peer
Packets in ENet are created with enet_packet_create(), where the size
of the packet must be specified. Optionally, initial data may be
specified to copy into the packet.
Certain flags may also be supplied to enet_packet_create() to control
various packet features:
ENET_PACKET_FLAG_RELIABLE specifies that the packet must use reliable
delivery. A reliable packet is guaranteed to be delivered, and a
number of retry attempts will be made until an acknowledgement is
received from the foreign host the packet is sent to. If a certain
number of retry attempts is reached without any acknowledgement, ENet
will assume the peer has disconnected and forcefully reset the
connection. If this flag is not specified, the packet is assumed an
unreliable packet, and no retry attempts will be made nor
acknowledgements generated.
A packet may be resized (extended or truncated) with
enet_packet_resize().
A packet is sent to a foreign host with
enet_peer_send(). enet_peer_send() accepts a channel id over which to
send the packet to a given peer. Once the packet is handed over to
ENet with enet_peer_send(), ENet will handle its deallocation and
enet_packet_destroy() should not be used upon it.
One may also use enet_host_broadcast() to send a packet to all
connected peers on a given host over a specified channel id, as with
enet_peer_send().
Queued packets will be sent on a call to enet_host_service().
Alternatively, enet_host_flush() will send out queued packets without
dispatching any events.
@code
/* Create a reliable packet of size 7 containing "packet\0" */
ENetPacket * packet = enet_packet_create ("packet",
strlen ("packet") + 1,
ENET_PACKET_FLAG_RELIABLE);
/* Extend the packet so and append the string "foo", so it now */
/* contains "packetfoo\0" */
enet_packet_resize (packet, strlen ("packetfoo") + 1);
strcpy (& packet -> data [strlen ("packet")], "foo");
/* Send the packet to the peer over channel id 0. */
/* One could also broadcast the packet by */
/* enet_host_broadcast (host, 0, packet); */
enet_peer_send (peer, 0, packet);
...
...
...
/* One could just use enet_host_service() instead. */
enet_host_flush (host);
@endcode
@section Disconnecting Disconnecting an ENet peer
Peers may be gently disconnected with enet_peer_disconnect(). A
disconnect request will be sent to the foreign host, and ENet will
wait for an acknowledgement from the foreign host before finally
disconnecting. An event of type ENET_EVENT_TYPE_DISCONNECT will be
generated once the disconnection succeeds. Normally timeouts apply to
the disconnect acknowledgement, and so if no acknowledgement is
received after a length of time the peer will be forcefully
disconnected.
enet_peer_reset() will forcefully disconnect a peer. The foreign host
will get no notification of a disconnect and will time out on the
foreign host. No event is generated.
@code
ENetEvent event;
enet_peer_disconnect (peer, 0);
/* Allow up to 3 seconds for the disconnect to succeed
* and drop any packets received packets.
*/
while (enet_host_service (client, & event, 3000) > 0)
{
switch (event.type)
{
case ENET_EVENT_TYPE_RECEIVE:
enet_packet_destroy (event.packet);
break;
case ENET_EVENT_TYPE_DISCONNECT:
puts ("Disconnection succeeded.");
return;
...
...
...
}
}
/* We've arrived here, so the disconnect attempt didn't */
/* succeed yet. Force the connection down. */
enet_peer_reset (peer);
...
...
...
@endcode
@section Connecting Connecting to an ENet host
A connection to a foreign host is initiated with enet_host_connect().
It accepts the address of a foreign host to connect to, and the number
of channels that should be allocated for communication. If N channels
are allocated for use, their channel ids will be numbered 0 through
N-1. A peer representing the connection attempt is returned, or NULL
if there were no available peers over which to initiate the
connection. When the connection attempt succeeds, an event of type
ENET_EVENT_TYPE_CONNECT will be generated. If the connection attempt
times out or otherwise fails, an event of type
ENET_EVENT_TYPE_DISCONNECT will be generated.
@code
ENetAddress address;
ENetEvent event;
ENetPeer *peer;
/* Connect to some.server.net:1234. */
enet_address_set_host (& address, "some.server.net");
address.port = 1234;
/* Initiate the connection, allocating the two channels 0 and 1. */
peer = enet_host_connect (client, & address, 2, 0);
if (peer == NULL)
{
fprintf (stderr,
"No available peers for initiating an ENet connection.\n");
exit (EXIT_FAILURE);
}
/* Wait up to 5 seconds for the connection attempt to succeed. */
if (enet_host_service (client, & event, 5000) > 0 &&
event.type == ENET_EVENT_TYPE_CONNECT)
{
puts ("Connection to some.server.net:1234 succeeded.");
...
...
...
}
else
{
/* Either the 5 seconds are up or a disconnect event was */
/* received. Reset the peer in the event the 5 seconds */
/* had run out without any significant event. */
enet_peer_reset (peer);
puts ("Connection to some.server.net:1234 failed.");
}
...
...
...
@endcode

* By default, access to unaligned memory is controlled by `memcpy()`, which is safe and portable.
* Unfortunately, on some target/compiler combinations, the generated assembly is sub-optimal.
* The below switch allow to select different access method for improved performance.
* Method 0 (default) : use `memcpy()`. Safe and portable.
* Method 1 : `__packed` statement. It depends on compiler extension (ie, not portable).
* This method is safe if your compiler supports it, and *generally* as fast or faster than `memcpy`.
* Method 2 : direct access. This method doesn't depend on compiler but violate C standard.
* It can generate buggy code on targets which do not support unaligned memory accesses.
* But in some circumstances, it's the only known way to get the most performance (ie GCC + ARMv6)
* See http://stackoverflow.com/a/32095106/646947 for details.

Q.Score is a measure of quality of the hash function.
It depends on successfully passing SMHasher test set.
10 is a perfect score.
A 64-bits version, named XXH64, is available since r35.
It offers much better speed, but for 64-bits applications only.
Name Speed on 64 bits Speed on 32 bits

These functions generate the xxHash of an input provided in multiple segments.
Note that, for small input, they are slower than single-call functions, due to state management.
For small input, prefer `XXH32()` and `XXH64()` .
XXH state must first be allocated, using XXH*_createState() .
Start a new hash by initializing state with a seed, using XXH*_reset().
Then, feed the hash state by calling XXH*_update() as many times as necessary.
Obviously, input must be allocated and read accessible.
The function returns an error code, with 0 meaning OK, and any other value meaning there is an error.
Finally, a hash value can be produced anytime, by using XXH*_digest().
This function returns the nn-bits hash as an int or long long.
It's still possible to continue inserting input into the hash state after a digest,
and generate some new hashes later on, by calling again XXH*_digest().
When done, free XXH state space if it was allocated dynamically.
