LuaJIT FFI file/directory iterator help needed

[Attila <ejjeliorjarat@...>]

Dear All,

Can somebody help me with LuaJIT FFI? I don't really understand it's  
mechanism, I used alien to iterate through a directory's files (I don't  
like os.execute with DIR/LS command, because it flashes the shell, and  
that's an ugly solution I think). This code worked well:

If that possible to rewrite it with LuaJIT, but without any additional  
dll? I don't know C/C++, I am mainly Lua programmer, so please help :)

Regards,
Attila
