Notes

• If called before the client updates the creature cache, GetCompanionInfo returns companions in the order in which they were learned by the current character (this can be observed during the first log-on after a patch or by removing the client's cache files). Once the cache is updated, however, it returns companions in alphabetical order; a COMPANION_UPDATE event is fired to notify of this update (however, multiple COMPANION_UPDATE events may be fired prior to the update as well). This was last verified in Patch 3.3.0a.
• This function was introduced in Patch 3.0.
