lua-socket: unix domain sockets? -


i'm using lua-socket 3.0rc1.3 (that comes ubuntu trusty) , lua 5.1. i'm trying listen on unix domain socket, , example code can find this

-- send stdin through unix socket socket = require"socket" socket.unix = require"socket.unix" c = assert(socket.unix()) assert(c:connect("/tmp/foo")) while 1     local l = io.read()     assert(c:send(l .. "\n")) end

problem is, when try , connect() "no such file or directory" - how create socket in first place? mkfifo /tmp/foo recommended me gets me "connection refused" error instead (i don't think fifo same thing domain socket?).

is there minimal working example out there of using luasocket on unix domain socket?

edit: paul's solution, here's mwe if anyone's interested

libsocket = require "socket" libunix = require "socket.unix" socket = assert(libunix()) socket="/tmp/socket" assert(socket:bind(socket)) assert(socket:listen()) conn = assert(socket:accept()) while 1     data=assert(conn:receive())     print("got line: " .. data)     conn:send("echo: " .. data .. "\n")     if data == "." conn:close() return end end

as far understand, can't create socket using mkfifo (or command) created (listening) server. there example listed on same page referenced, may difficult find:

sock, err = s:listen([backlog|_32_]) sock, err = s:bind(path) client_conection, err = s:accept()

basically, create server same way you'd tcp, instead of binding address/port, bind path , start accepting new connections on it.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
