How to check if a item still exists?

[daniellumertz]

is there a API to check if a item/track/take anything still exist?

(the thing existed in the start of the script but it might be (proposaly) deleted)

[Meo-Ada Mespotine]

function DoesItemExist(Item)
  return pcall (reaper.IsMediaItemSelected, Item)
end

This returns true, if the MediaItem exists or false if it doesn't exist anymore.
If false, the second returnvalue holds the error-message that happened.

(This function doesn't check, if Item is a valid MediaItem, but you can add this using reaper.ValidatePtr() )

Edit: I think, I'll add that to Ultraschall-API as well. This could be helpful I think.
