<h2><a name="functions"></a>Functions</h2>
<dl class="function">


<dt><a name="Socket.accept"></a><strong>Socket:accept</strong>&nbsp;()</dt>
<dd>

 Accept a connection on the socket.


<h3>Return values:</h3>
<ol>
	
	<li>Socket Object
	
	<li>Peer IP-Address
	
	<li>Peer Port
	
</ol>


</dd>


<dt><a name="Socket.bind"></a><strong>Socket:bind</strong>&nbsp;(host, port)</dt>
<dd>

 Bind the socket to a network address.


<h3>Parameters</h3>
<ul>
	
	<li>
	  host: Host (optional, default: all addresses)
	</li>
	
	<li>
	  port: Port or service description
	</li>
	
</ul>


<h3>Usage</h3>
<ul>
	
	<li>This function calls getaddrinfo() and bind() but NOT listen().
	
	<li>If <em>host</em> is a domain name it will be looked up and bind()  
 tries the IP-Addresses in the order returned by the DNS resolver 
 until the bind succeeds. 
	
	<li>UNIX sockets ignore the <em>port</em>, 
 and interpret <em>host</em> as a socket path.
	
</ul>


<h3>Return value:</h3>
true


</dd>


<dt><a name="Socket.close"></a><strong>Socket:close</strong>&nbsp;()</dt>
<dd>

 Close the socket.


<h3>Return value:</h3>
true


</dd>


<dt><a name="Socket.connect"></a><strong>Socket:connect</strong>&nbsp;(host, port)</dt>
<dd>

 Connect the socket to a network address.


<h3>Parameters</h3>
<ul>
	
	<li>
	  host: Hostname or IP-Address (optional, default: localhost)
	</li>
	
	<li>
	  port: Port or service description
	</li>
	
</ul>


<h3>Usage</h3>
<ul>
	
	<li>This function calls getaddrinfo() and connect().
	
	<li>If <em>host</em> is a domain name it will be looked up and connect()  
 tries the IP-Addresses in the order returned by the DNS resolver 
 until the connect succeeds. 
	
	<li>UNIX sockets ignore the <em>port</em>, 
 and interpret <em>host</em> as a socket path.
	
</ul>


<h3>Return value:</h3>
true


</dd>


<dt><a name="Socket.fileno"></a><strong>Socket:fileno</strong>&nbsp;()</dt>
<dd>

 Get the number of the filedescriptor.


<h3>Return value:</h3>
file descriptor number


</dd>


<dt><a name="Socket.getopt"></a><strong>Socket:getopt</strong>&nbsp;(level, option)</dt>
<dd>

 Get a socket option.


<h3>Parameters</h3>
<ul>
	
	<li>
	  level: Level ["socket", "tcp", "ip", "ipv6"]
	</li>
	
	<li>
	  option: Option	["keepalive", "reuseaddr", "sndbuf", "rcvbuf",  
 "priority", "broadcast", "linger", "sndtimeo", "rcvtimeo", "dontroute",  
 "bindtodevice", "error", "oobinline", "cork" (TCP),  "nodelay" (TCP),

</dd>


<dt><a name="Socket.read  "></a><strong>Socket:read  </strong>&nbsp;(length)</dt>
<dd>

 Receive a message on the socket (This is an alias for recv). 
 See the recvfrom description for more details.


<h3>Parameters</h3>
<ul>
	
	<li>
	  length: Amount of data to read (in Bytes).
	</li>
	
</ul>


<h3>Return value:</h3>
buffer containing data successfully read


<h3>See also:</h3>
<ul>
	
	<li><a href="#Socket.recvfrom">
		Socket:recvfrom
	</a>
	
</ul>

</dd>


<dt><a name="Socket.recv  "></a><strong>Socket:recv  </strong>&nbsp;(length)</dt>
<dd>

 Receive a message on the socket. 
 This function is identical to recvfrom except that it does not return  
 the sender's source address. See the recvfrom description for more details.


<h3>Parameters</h3>
<ul>
	
	<li>
	  length: Amount of data to read (in Bytes).
	</li>
	
</ul>


<h3>Return value:</h3>
buffer containing data successfully read


<h3>See also:</h3>
<ul>
	
	<li><a href="#Socket.recvfrom">
		Socket:recvfrom
	</a>
	
</ul>

</dd>


<dt><a name="Socket.recvfrom"></a><strong>Socket:recvfrom</strong>&nbsp;(length)</dt>
<dd>

 Receive a message on the socket including the senders source address.


<h3>Parameters</h3>
<ul>
	
	<li>
	  length: Amount of data to read (in Bytes).
	</li>
	
</ul>


<h3>Usage</h3>
<ul>
	
	<li><strong>Warning:</strong> It is not guaranteed that all requested data 
 is read at once. 
 You have to check the return value - the length of the buffer actually read - 
 or use the safe IO functions in the high-level IO utility module.
	
	<li>The length of the return buffer is limited by the (compile time)  
 nixio buffersize which is <em>nixio.const.buffersize</em> (8192 by default). 
 Any read request greater than that will be safely truncated to this value.  
	
</ul>


<h3>Return values:</h3>
<ol>
	
	<li>buffer containing data successfully read
	
	<li>host		IP-Address of the sender
	
	<li>port		Port of the sender
	
</ol>


</dd>


<dt><a name="Socket.send"></a><strong>Socket:send</strong>&nbsp;(buffer, offset, length)</dt>
<dd>

 Send a message on the socket. 
 This function is identical to sendto except for the missing destination 
 parameters. See the sendto description for a detailed description.


<h3>Parameters</h3>
<ul>
	
	<li>
	  buffer: Buffer holding the data to be written.
	</li>
	
	<li>
	  offset: Offset to start reading the buffer from. (optional)
	</li>
	
	<li>
	  length: Length of chunk to read from the buffer. (optional)
	</li>

<dt><a name="Socket.sendto"></a><strong>Socket:sendto</strong>&nbsp;(buffer, host, port, offset, length)</dt>
<dd>

 Send a message on the socket specifying the destination.


<h3>Parameters</h3>
<ul>
	
	<li>
	  buffer: Buffer holding the data to be written.
	</li>
	
	<li>
	  host: Target IP-Address
	</li>
	
	<li>
	  port: Target Port
	</li>
	
	<li>
	  offset: Offset to start reading the buffer from. (optional)
	</li>
	
	<li>
	  length: Length of chunk to read from the buffer. (optional)
	</li>
	
</ul>


<h3>Usage</h3>
<ul>
	
	<li><strong>Warning:</strong> It is not guaranteed that all data 
 in the buffer is written at once. 
 You have to check the return value - the number of bytes actually written - 
 or use the safe IO functions in the high-level IO utility module.
	
	<li>Unlike standard Lua indexing the lowest offset and default is 0.
	
</ul>


<h3>Return value:</h3>
number of bytes written
