ios.eof? â true or false
Instance Public methods
Returns true if ios is at end of file that means there are no more
data to read. The stream must be opened for reading or an
IOError will be raised.
f = File.new("testfile")
dummy = f.readlines
f.eof #=> true
If ios is a stream such as pipe or socket, IO#eof?
blocks until the other end sends some data or closes it.
r, w = IO.pipe
Thread.new { sleep 1; w.close }
r.eof? #=> true after 1 second blocking
r, w = IO.pipe
