	@doc: socket
	@keyterms:
		socket object class
	@title:
		socket class
	@type:
		class
	@short:
		A Ipv4/Ipv6 TCP socket
	@inherits:
		[class]object[/class]
	@description:
		This class provides a standard TCP/IP socket functionality.[br]
		It can be used either for connecting to a remote host or to listening for incoming connections.[br]
		If the KVIrc executable has been compiled with the IPV6 protocol support , this socket also supports it.[br]
	@functions:
		!fn: $status()
		Returns the status of the socket :[br]
		4=connected[br]
		3=listening[br]
		2=connecting[br]
		1=in dns call[br]
		0=disconnected

		!fn: $connectTimeout()
		Returns the value of the connect attempt timeout in milliseconds.[br]
		This is the timeout after that a connection attempt will be considered as failed if the remote
		host is not responding. You can set it with [classfnc:socket]$setConnectTimeout[/classfnc]().

		!fn: $setConnectTimeout(<timeout>)
		Sets the connect timeout for this socket. <timeout> must be a positive value in milliseconds.[br]
		The default timeout is 60000.

		!fn: $connect(<host>,<port>)
		Attempts a connection to <host> on port <port>.[br]
		<host> can be a numeric internet address (either Ipv4 or Ipv6 (if supported)) or a hostname.[br]
		If a hostname is used, a DNS lookup is performed (the socket enters the "dns call" state).[br]
		This function returns 1 if the connect attempt can be succesfully initiated,
		0 otherwise.[br] In fact , this function returns 0 only if the supplied <port> parameter
		is invalid or the socket is in an incoherent state (already connected or listening):
		for a newly created socket and with a valid <port> number you can safely ignore
		the return value.[br]
		Please note that the connection is asynchronous: when this function returns
		the socket is NOT connected: it has just initiated the connect attempt
		and you will be notified of the attempt result by an asynchronous event call:
		in case of failure , $connectFailedEvent() will be called , in case of
		succes , $connectEvent() will be called.

		!fn: $listen([<port>[,<interface>[,<force_ipv6>]]])
		Attempts to listen on the specified <port> and <interface>.[br]
		If <port> is not passed it is assumed to be 0 , if <interface> is not passed , it is assumed to be
		"any interface" (INADDR_ANY).[br] Port 0 means that the kernel should choose a "random" port to listen on.[br]
		If the <interface> is recognized as IPV6 address , and IPV6 is supported , the socket listens
		in IPV6 mode. If <interface> is an empty string and <force_ipv6> is 1 the socket listens
		on "any ipv6 interface".[br]
		This function returns '1' in case of success and '0' in case of failure.[br]
		On some systems listening in the IPV6 namespace allows to accept also IPV4 connections (this includes
		linux but not windows afaik).[br]
		When an incoming connection will arrive , $incomingConnectionEvent() will be called.

		!fn: $accept(<socketId>)
		This function can be called only from inside $incomingConnectionEvent().[br]
		<socketId> must be a newly created socket sub-class instance object.[br]
		The passed object will be set up to handle the incoming connection and this object
		will remain in listening state (unless you explicitly close it).[br]
		This function returns '1' in case of success and '0' in case of failure.

		!fn: $connectEvent()
		This function is called when a connection attempt has been succesfully completed.
		The socket is actually connected to [classfnc:socket]$remoteIp[/classfnc]() on
		[classfnc:socket]$remotePort[/classfnc](). You can start
		writing data and you may expect [classfnc:socket]$dataAvailableEvent[/classfnc]() to be
		triggered.

		!fn: $incomingConnectionEvent()
		This function is called when an incoming connection arrives over a socket in listening state.[br]
		You must call [classfnc:socket]$accept[/classfnc]() passing a newly created socket object
		to accept and handle the connection.[br] If you don't call [classfnc:socket]$accept[/classfnc]()
		the incoming connection will be automatically terminated.

		!fn: $connectFailedEvent(<reason>)
		This function is called when a connection attempt fails for some reason. <reason> contains
		the error string.[br]
		This function may be called only between a call to [classfnc:socket]$connect[/classfnc]() and
		the [classfnc:socket]$connectEvent[/classfnc]().

		!fn: $disconnectEvent([error])
		This function is called when a connection is terminated either cleanly or because of an error.[br]
		[error] is an empty string in case of a "clean" termination (connection closed by the remote host)
		or is a message describing the socket error that caused the connection to be interrupted.

		!fn: $dataAvailableEvent(<data_length>)
		This function is called when some data is available to be read: the <data_length> parameter specifies
		the length of the available data in bytes.[br]
		You can use one of the $read* functions to obtain the data.

		!fn: $read(<length>)
		Reads at most <length> bytes of data from the socket. If <length> is anything "outside" the
		available data range (<length> < 0 or <length> > available_data_length), this function
		returns all the available data.[br]
		Please note that this function can't deal withi binary data: NULL characters are transformed to
		ASCII characters 255.

		!fn: $readHex(<length>)
		Reads at most <length> bytes of data from the socket. If <length> is anything "outside" the
		available data range (<length> < 0 or <length> > available_data_length), this function
		returns all the available data.[br]
		Returns the data encoded as hexadecimal digit string: this function can deal with binary data too.

		!fn: $write(<data>)
		Writes <data> to the socket.[br]
		This function can't deal with binary data (you can't send a NULL character)[br]
		Please note that when this function finishes it does not mean that the data has reached the remote end.[br]
		Basically it does not even mean that the data has been sent to the remote host.[br]
		The data is enqueued for sending and will be sent as soon as possible.[br]
		If you're going to [cmd]delete[/cmd] this object just after the $write call, you should
		call [classfnc:socket]$close[/classfnc]() just before [cmd]delete[/cmd] to ensure the data delivery.

		!fn: $writeHex(<hex_data>)
		Writes <data> to the socket.[br]
		<data> is expected to be a hexadecimal rappresentation of the bytes to be sent (two HEX characters
		for each byte). This means that the length of <hex_data> string must be a multiple of 2.[br]
		Returns the length of the actually decoded and sent data in bytes or -1 in case of error (the string
		was not a valid hexadecimla rappresentation).[br]
		Please note that when this function finishes it does not mean that the data has reached the remote end.[br]
		Basically it does not even mean that the data has been sent to the remote host.[br]
		The data is enqueued for sending and will be sent as soon as possible.[br]
		If you're going to [cmd]delete[/cmd] this object just after the $writeHex call, you should
		call [classfnc:socket]$close[/classfnc]() just before [cmd]delete[/cmd] to ensure the data delivery.

		!fn: $close()
		Resets this socket state: kills any pending or active connection. After a close() call
		the socket may be used for a new connection.[br]
		If there is an active connection, there is a last attempt to flush the pending outgoing data.[br]
		You don't need to call $close() if you [cmd]delete[/cmd] the socket: KVIrc will
		reset the socket state automatically and free the memory. But if you want to ensure data delivery
		after a $write call sequece and just before a [cmd]delete[/cmd], $close() is the only chance to do it.

		!fn: $remoteIp()
		Returns the IP address of the remote end of this socket.[br]
		The return value is meaningful only if the socket is in connected or connecting state.

		!fn: $setProtocol(<protocol>)
		Let KVIrc use TCP jr UDP protocol

		!fn: $remotePort()
		Returns the port of the remote end of this socket.[br]
		The return value is meaningful only if the socket is in connected or connecting state.

		!fn: $localIp()
		Returns the IP address of the local end of this socket.[br]
		The return value is meaningful only if the socket is in connected , listening or connecting state.

		!fn: $localPort()
		Returns the port of the local end of this socket.[br]
		The return value is meaningful only if the socket is in connected , listening or connecting state.
