title: What is a VoidString object?
body: <p>I am programming a LUA Dissector for Wireshark and have read about a VoidString object which could be passed by while creating a ProtoField object. See <a href="https://wiki.wireshark.org/LuaAPI/Proto#ProtoField" rel="nofollow noreferrer">https://wiki.wireshark.org/LuaAPI/Proto#ProtoField</a> for more information. I would like to no more about this object and what's the purpose of using it. If I am clicking on the link ''VoidString'' an empty page is getting displayed unfortunately because the documentation for this object seems to be missed. I have googled it but found nothing. Any Ideas?</p>
  
  <p>Thanks in Advance!</p>
