[Freeswitch-dev] please shed me light on code reading

[Michael Jerris]

a variable is a channel variable that you can access in the dial-plan, in events, etc.  A private is a void pointer that we use to store data that is later accessed by name in the application.  The code you were talking about below was added to support loopback channel:
