--- !ruby/object:RI::MethodDescription aliases: [] block_params: comment: - !ruby/struct:SM::Flow::P body: Returns true if <em>ios</em> is at end of file that means there are no more data to read. The stream must be opened for reading or an <tt>IOError</tt> will be raised. - !ruby/struct:SM::Flow::VERB body: " f = File.new(&quot;testfile&quot;)\n dummy = f.readlines\n f.eof #=&gt; true\n" - !ruby/struct:SM::Flow::P body: If <em>ios</em> is a stream such as pipe or socket, <tt>IO#eof?</tt> blocks until the other end sends some data or closes it. - !ruby/struct:SM::Flow::VERB body: " r, w = IO.pipe\n Thread.new { sleep 1; w.close }\n r.eof? #=&gt; true after 1 second blocking\n\n r, w = IO.pipe\n Thread.new { sleep 1; w.puts &quot;a&quot; }\n r.eof? #=&gt; false after 1 second blocking\n\n r, w = IO.pipe\n r.eof? # blocks forever\n" - !ruby/struct:SM::Flow::P body: Note that <tt>IO#eof?</tt> reads data to a input buffer. So <tt>IO#sysread</tt> doesn't work with <tt>IO#eof?</tt>. full_name: IO#eof? is_singleton: false name: eof? params: | ios.eof => true or false ios.eof? => true or false visibility: public
