Hello everyone,
IO::Select works very well for me, but it still holds some mysteries
for me. In particular: when will I get it to return due to an error?
More to the point, let’s say I have:
read, write, error = IO::Select([some_io], [some_io], [some_io])
When will I get “error” to be something other than an empty array? I
used it with sockets, and having the socket remotely closed
apparently did not help provoke it.
