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.
