Hello,

I have a C shared library. I am writing a node module for this library. I 
wrote a process function which can be accessed from JS and it calls my 
shared library function. In JS, it looks like,

myLibrary.process(args, function(output) {
});

I am wondering, is this a non-blocking call or blocking one? Since I am not 
doing anything special to make it non-blocking, I assume this will be a 
blocking call. Or is Node doing something to make it non-blocking?

If the above code is blocking, how do I make a non-blocking wrapper for 
this shared library? Should I use work queues from libuv?

Any help would be great!

Thanks
Navaneeth
