In Roadshow, bsdsocket.library is always available, so checking Socket Library Open for 0 won't work. How else can we detect that there's no internet connection without making a network request that fails?

  • Looking for interfaces?
  • Other?

Async Writing

  • Break down existing logic flow, make sure return values are all correct.
  • Test with timeout. Is the correct handling being done?
  • "Uninstall" Roadshow when done by moving bsdsocket.library out of the way.

Current solution:

  • Do a DNS check to a known remote server. This is how IBrowse first determines connectivity.
  • Attempt an initial connect with a reasonably sized timeout (5 seconds is probably enough). If that fails, you likely don't have a connection.
