Summary

Function: llOpenRemoteDataChannel( );

Creates a channel to listen for XML-RPC calls. Will trigger a remote_data event with channel id once it is available.

Caveats

  • This function causes the script to sleep for 1.0 seconds.
  • If an object moves from one region to another it must re-open the channel
    • The object will get the *same* channel as before, but without re-opnening no requests will get through
  • Any channel that is not used for 14 days will be cleaned up.
    • May be advisable to somewhat regularly (before expected use or on a regular shedule) check that the channel is good and hasn't changed by calling llOpenRemoteDataChannel and comparing to the previous channel.
