[libtorrent] Torrent error handling

[Oscar A. O. E. <osc...@gm...>]

Hi everybody.
I´m trying to implement a clean way to get torrent error conditions  
the same way I´m retrieving torrent_status like  
torrent_status::downloading or torrent_status::seeding.
I was unable to find such a functionality. Tried with the pop_alert ()  
like in client_test.cpp but I don´t get nothing popped out, although I 
´m working with a torrent file with a known non existent tracker. Why  
are the alert stacks session oriented? And how can you find the  
failing torrent in session and the corresponding error status?
My need is to manage some (high level) rough error conditions like:

Tracker not Responding.
No network.
....

In the api doc there is a mention to torrent_status::error, but only  
in the doc. or am I missing something.
And I´m also confused whit this documentation entries:

  struct torrent_alert: alert
{
         // ...
         torrent_handle handle;
};

What are the missing struct elements

On the other hand: is there a way to assign a "no activity" torrent  
timeout. Like download progress being zero for a given period of time?  
(No peers?)

Many thanks!

PS: Using Libtorrent 0.13.1
