Hello Navaneeth, One cannot ascertain from the JS code whether the call is going to block the event loop or not. In libev, you would register a ev_io watcher and listen for EV_READ, EV_WRITE (or both) events (ev_io_init() + ev_io_start()) whenever the FD becomes readable/writable. I think the equivalent of it is uv_poll_init() + uv_poll_start() in libuv.
Here is an example of the implementation in zeromq.node: https://github.com/JustinTulloss/zeromq.node/blob/master/binding.cc#L312 Can you shed more light on what C shared library are you trying to bridge??
