<p>The <a class="reference external" href="reference-Session.html#pop_alerts()">pop_alerts()</a> function on <a class="reference external" href="reference-Session.html#session">session</a> is the main interface for retrieving
|
|
alerts (warnings, messages and errors from libtorrent). If no alerts have
|
|
been posted by libtorrent <a class="reference external" href="reference-Session.html#pop_alert()">pop_alert()</a> will return an empty list.</p>
|
|
<p>By default, only errors are reported. <a class="reference external" href="reference-Session.html#set_alert_mask()">set_alert_mask()</a> can be used to
|
|
specify which kinds of events should be reported. The <a class="reference external" href="reference-Alerts.html#alert">alert</a> mask is
|
|
comprised by bits from the <a class="reference external" href="reference-Alerts.html#category_t">category_t</a> enum.</p>
|
|
<p>Every <a class="reference external" href="reference-Alerts.html#alert">alert</a> belongs to one or more category. There is a small cost involved
|
|
in posting alerts. Only alerts that belong to an enabled category are
|
|
posted. Setting the <a class="reference external" href="reference-Alerts.html#alert">alert</a> bitmask to 0 will disable all alerts (except those
|
|
that are non-discardable).</p>
|
|
<p>There are other <a class="reference external" href="reference-Alerts.html#alert">alert</a> base classes that some alerts derive from, all the
|
|
alerts that are generated for a specific torrent are derived from
|
|
<a class="reference external" href="reference-Alerts.html#torrent_alert">torrent_alert</a>, and tracker events derive from <a class="reference external" href="reference-Alerts.html#tracker_alert">tracker_alert</a>.</p>
