+To use **BlueSocket** to listen for a connection on a socket the following API is provided:
 - `listen(on port: Int, maxBacklogSize: Int = Socket.SOCKET_DEFAULT_MAX_BACKLOG, allowPortReuse: Bool = true, node: String? = nil)`
 The first parameter `port`, is the port to be used to listen on. The second parameter, `maxBacklogSize` allows you to set the size of the queue holding pending connections. The function will determine the appropriate socket configuration based on the `port` specified.  For convenience on macOS, the constant `Socket.SOCKET_MAX_DARWIN_BACKLOG` can be set to use the maximum allowed backlog size.  The default value for all platforms is `Socket.SOCKET_DEFAULT_MAX_BACKLOG`, currently set to *50*. For server use, it may be necessary to increase this value.  To allow the reuse of the listening port, set `allowPortReuse` to `true`.  If set to `false`, a error will occur if you attempt to listen on a port already in use.  The `DEFAULT` behavior is to `allow` port reuse.  The last parameter, `node`, can be used to listen on a *specific address*.  The value passed is an *optional String* containing the numerical network address (for IPv4, numbers and dots notation, for iPv6, hexidecimal strting).  The `DEFAULT` behavior is to search for an appropriate interface.  If `node` is improperly formatted a **SOCKET_ERR_GETADDRINFO_FAILED** error will be returned.  If `node` is properly formatted but the address specified is not available, a **SOCKET_ERR_BIND_FAILED** will be returned.
