A simple synchronous TCP library for Node.js. This is implemented as a [native addon] (http://nodejs.org/api/addons.html).
Note before proceeding that Node is designed to be an asynchronous environment, and if you want to use this module you should have a really good reason to do so.
Currently only the client part is implemented, with the ability to open a connection to the server, read/write to the connection, and close the connection. The server part isn't implemented yet, as I can't think of a useful use case for it.
For example, this module is developed for the DiffBug
project, in which it's used to synchronize between a client process and a server
process. When the client needs to wait for an event to occur, it connects to the
server using this module and blocks on a synchronous
read(). The server only
writes to the connection when the event occurs.
In most programs, this functionality can be implemented using the asynchronous
module as well, but DiffBug is an automated debugging tool: it needs to be able to
pause at any point in the user's code by inserting a function call at that point.
Therefore, only synchronous blocking can do the trick.
One simple way to achieve synchronous blocking in Node.js is to call
on a Unix named pipe. However this isn't as flexible as using TCP and it doesn't work
