v3.3.0

add socket.dontwait(bool) option for controlling libnanomsg flag NN_DONTWAIT

socket.dontwait(boolean)

(Function, param: Boolean, default: true, except PUSH sockets): Sets the NN_DONTWAIT flag, specifying that the operation should be performed in non-blocking mode,

• true for non-blocking mode
• false for blocking mode

Pass no parameter for the socket's current mode.

socket.dontwait(false);
console.log(socket.dontwait()); // false

// or set when socket is started:
require('nanomsg').socket('pub', { dontwait: false });
