##Installation

npm install 

##Usage

var http = require('http'),
	unixSocket = require("unix-socket");

var server = http.Server();

var option = { 
	path: "/var/run/shm/nodejs/server.sock",
	mode: 0666 
};

unixSocket.listen(server, option, function(result) {
	if (result) {
		console.log('Server started on ' + result);
	} else {
		console.error('Error');
		process.exit(0);
	}
});

##Option

var option = { 
	path: "/var/run/shm/nodejs/server.sock",
	mode: 0666 
};

//or

var option = { 
	path: [ "/var/run/shm/nodejs/server1.sock", "/var/run/shm/nodejs/server2.sock" ]
	mode: 0666 
};

##Methods ###isStreamOpen(path, callback) return boolean

var result = unixSocket.isStreamOpen(path);

//or

unixSocket.isStreamOpen(path, function(result) {

});

###prepareStream(path, callback) return boolean

var result = unixSocket.prepareStream(path);

//or

unixSocket.prepareStream(path, function(result) {

});

###availableStream(paths, callback) return path(string)

var tryList = [ "/var/run/shm/nodejs/server1.sock", "/var/run/shm/nodejs/server2.sock" ];
var path = unixSocket.availableStream(tryList);

//or

unixSocket.availableStream(tryList, function(path) {

});

###listen(server, option, callback) Prepare unix socket, unlink first if exists.
