No, not with `io.open`. You need some OS-specific module for that.
My earlier question seems to have fallen in the bit bucket. It was is there any way to tell whether a named fifo has data in it before reading it since if the fifo is empty the read will block until another process puts something into the fifo.
With `luaposix` you could use `fileno` and `rpoll`. `posix.open` can also open a file in non-blocking mode.
