Hey all – Can anyone point me to the documentation (or the source!) that defines the IO.expect method (parameters, return values, etc.)? I can’t seem to find it anywhere. Also, I’m interested in extending this routine to use Floats (not just Fixnums) as timeout values (for a granularity of, say, 50 milliseconds). Thanks, – Dan C. ---

I do not know about that. Could you mean REXML.expected? That is the closest thing I can think. [RDoc Documentation](http://ruby-doc.org/core/) should have most all the documentation there is. ---

Creating an IO object: i = IO.new 2 ( the handle for stderr ) Then doing: i.methods.sort Returns no method expect. Are you using some library that extends the IO class? ---

Thanks, Jordan! So it looks like the timeout value is really only passed to IO#select. Would this imply then that Floats as well as Fixnums could be used? I personally don’t see why not, but the docs clearly say only a Fixnum can be used as a timeout value. [shrug] What do y’all think? Rgds, – Dan ---
