NAME

       dnsjit.output.udpcli - Simple and dumb UDP DNS client

SYNOPSIS

         local output = require("dnsjit.output.udpcli").new("127.0.0.1", "53")

DESCRIPTION

       Simple and rather dumb DNS client that takes any payload you give it and sends the full payload over UDP.

   Attributes
       timeout
              A core.timespec that is used when producing objects.

   Functions
       Udpcli.new()
              Create a new Udpcli output.

       Udpcli:timeout(seconds, nanoseconds)
              Set the timeout when producing objects.

       Udpcli:connect(host, port)
              Connect to the host and port and return 0 if successful.

       Udpcli:nonblocking(bool)
              Enable  (true)  or  disable  (false)  nonblocking  mode and return 0 if successful, if bool is not
              specified then return if nonblocking mode is on (true) or off (false).

       Udpcli:receive()
              Return the C functions and context for receiving objects, these objects will be sent.

       Udpcli:produce()
              Return the C functions and  context  for  producing  objects,  these  objects  are  received.   If
              nonblocking  mode  is  enabled the producer will return a payload object with length zero if there
              was nothing to receive.  If nonblocking mode is disabled the producer will wait for  data  and  if
              timed  out  (see  timeout) it will return a payload object with length zero.  The producer returns
              nil on error.

       Udpcli:packets()
              Return the number of "packets" sent, actually the number of completely sent payloads.

       Udpcli:received()
              Return the number of "packets" received, actually the number of successful  calls  to  recvfrom(2)
              that returned data.

       Udpcli:errors()
              Return the number of errors when sending or receiving.
