NAME

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

SYNOPSIS

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

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

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.
