Subject: Re: How to set socket option SO_RCVTIMEO

hehe yeh I just realized I could use a regular Socket instead of a TCP 
Socket -- it doesn't appear to be the only problem though.  here's my 
latest code (which still doesn't timeout properly)


require 'socket'

opt = [1, 500_000].pack("I_2")

sock = Socket.new(Socket::AF_INET, Socket::SOCK_STREAM, 0)
sockaddr = Socket.pack_sockaddr_in(3232, '192.168.1.10')

sock.setsockopt(Socket::SOL_SOCKET, Socket::SO_RCVTIMEO, opt)
puts "sockopt = #{sock.getsockopt(Socket::SOL_SOCKET, 
Socket::SO_RCVTIMEO).inspect}"

sock.connect(sockaddr)

#this tells the server at 192.168.1.10:3232 to wait 10 seconds before 
responding, so we should get a timeout on our socket
sock.write("10\r\n")

start_time = Time.now
result = sock.gets
time = Time.now - start_time

puts "read: #{sock.gets} after: #{time} seconds"
#no timeout occured, this read returns after 10 seconds
