### tty.getColumns() ### tty.setWindowSize(fd, row, col)
Returns the number of columns associated with the current process's TTY. `ioctl`s the window size settings to the file descriptor.
Note that each time this number is changed the process receives a `SIGWINCH`
signal. So you can keep a cache of it like this: ### tty.getWindowSize(fd)
var columns = tty.getColumns(); Returns `[row, col]` for the TTY associated with the file descriptor.
process.on('SIGWINCH', function() {
columns = tty.getColumns();
});
