<para>
|
|
<classname>EvIdle</classname>
|
|
watchers trigger events when no other events of the same or higher
|
|
priority are pending (
|
|
<classname>EvPrepare</classname>
|
|
,
|
|
<classname>EvCheck</classname>
|
|
and other
|
|
<classname>EvIdle</classname>
|
|
watchers do not count as receiving
|
|
<emphasis>events</emphasis>
|
|
).
|
|
</para>
|
|
<para>
|
|
Thus, as long as the process is busy handling sockets or timeouts(or even
|
|
signals) of the same or higher priority it will not be triggered. But when
|
|
the process is in idle(or only lower-priority watchers are pending), the
|
|
<classname>EvIdle</classname>
|
|
watchers are being called once per event loop iteration - until stopped,
|
|
that is, or the process receives more events and becomes busy again with
|
|
higher priority stuff.
|
|
</para>
|
|
<para>
|
|
Apart from keeping the process non-blocking(which is a useful on its own
|
|
sometimes),
|
|
<classname>EvIdle</classname>
|
|
watchers are a good place to do
|
|
<emphasis>"pseudo-background processing"</emphasis>
|
|
, or delay processing stuff to after the event loop has handled all
|
|
outstanding events.
|
|
</para>
|
|
<para>
|
|
The most noticeable effect is that as long as any
|
|
<emphasis>idle</emphasis>
|
|
watchers are active, the process will
|
|
<emphasis>not</emphasis>
|
|
block when waiting for new events.
