webrtc/peerconnection/samples/client/linux/main_wnd.h
tommi@webrtc.org 102b2270c7 First version of the peerconnection client application for Linux.
I made several updates to the Windows version as well so that both
implementations share
a big portion of the code.
The underlying PeerConnection notifications have changed a bit since the last
update
so that there's still a known issue that I plan to fix in my next change:

  // TODO(tommi): There's a problem now with terminating connections:
  // When ending a conversation, both peers now send a signaling message
  // that indicates that their ports are closed (port=0).  The trouble this
  // causes us here is that we can interpret such a message as an invite
  // to a new conversation.  So, currently there is a bug that ending
  // a conversation can immediately start a new one.
  // To fix this I plan to change how conversations start and have a special
  // notification message via the server that prepares a client for a
  // conversation instead of automatically recognizing the first signaling
  // message as an invite.
