Emblem-important-red.png Security Warning!

It is a terrible idea to tie any security measures to display names; they are not unique and can easily be changed.

Emblem-important-red.png Data Execution Warning!

Display names can contain quotes and some punctuation. While this is not a problem for LSL, remember to escape strings being passed to command line scripts, sql queries, etc.

Summary

Function: key llRequestDisplayName( key id );

Requests the Display Name of the agent identified by id. When the Display Name is available the dataserver event will be raised. The agent identified by id does not need to be in the same region or online at the time of the request.
Returns the handle (a key) that is used to identify the dataserver event when it is raised.

• key id avatar UUID

Caveats

  • If the request fails for any reason, there will be no error notice or dataserver event. You may use a timer to check for stale requests.
  • If you merely wish to show the agent display name in the viewer window, it may be more straightforward to use Viewer URI Name Space and avoid a dataserver event, e.g.:
    llSay(0, "secondlife:///app/agent/" + (string)id + "/displayname");
