Lookup the current process's TTY device


Get the TTY device (e.g., /dev/pts/3) of the current node process

// A clone of the `tty` command 
var tty = require('spotty');
tty(function(err, res) {
    if (err) {
        console.error("Error found: " + err.toString())
    } else {

It's an ugly hack, but it should work. The idea is to call fstat on file descriptor 0, and then to call stat on all tty-like files in dev. Stop when we find one that matches fstat(0).

Doesn't work on Windows. Should work on OSX and Linux, but needs some testing. Won't work if fd=0 isn't standard input connected to a TTY.
