<tr><td colspan="2"><div class="groupText"><p>These functions are used to safely tear down an event in a multithreaded application.</p>
<p>If you construct your events with EV_FINALIZE to avoid deadlocks, you will need a way to remove an event in the certainty that it will definitely not be running its callback when you deallocate it and its callback argument.</p>
<p>To do this, call one of event_finalize() or event_free_finalize with 0 for its first argument, the event to tear down as its second argument, and a callback function as its third argument. The callback will be invoked as part of the event loop, with the event's priority.</p>
<p>After you call a finalizer function, <a class="el" href="event_8h.html#ab0c85ebe9cf057be1aa17724c701b0c8" title="Add an event to the set of pending events.">event_add()</a> and <a class="el" href="event_8h.html#a31d9440cf2b7010e32a05a2142a91525" title="Make an event active.">event_active()</a> will no longer work on the event, and <a class="el" href="event_8h.html#a2ffc10a652c67bea16b0a71f7d5a44dc" title="Remove an event from the set of monitored events.">event_del()</a> will produce a no-op.

Once the callback has been invoked, you should treat the event structure as containing uninitialized memory.</p>
<p>The event_free_finalize() function frees the event after it's finalized; event_finalize() does not.</p>
<p>A finalizer callback must not make events pending or active. It must not add events, activate events, or attempt to "resuscitate" the event being finalized in any way.</p>

<p>Prepare a new, already-allocated event structure to be added. </p>
<p>The function <a class="el" href="event_8h.html#a3e49a8172e00ae82959dfe64684eda11" title="Prepare a new, already-allocated event structure to be added.">event_assign()</a> prepares the event structure ev to be used in future calls to <a class="el" href="event_8h.html#ab0c85ebe9cf057be1aa17724c701b0c8" title="Add an event to the set of pending events.">event_add()</a> and <a class="el" href="event_8h.html#a2ffc10a652c67bea16b0a71f7d5a44dc" title="Remove an event from the set of monitored events.">event_del()</a>. Unlike <a class="el" href="event_8h.html#a6cd300e5cd15601c5e4570b221b20397" title="Allocate and assign a new event structure, ready to be added.">event_new()</a>, it doesn't allocate memory itself: it requires that you have already allocated a struct event, probably on the heap. Doing this will typically make your code depend on the size of the event structure, and thereby create incompatibility with future versions of Libevent.</p>
<p>The easiest way to avoid this problem is just to use <a class="el" href="event_8h.html#a6cd300e5cd15601c5e4570b221b20397" title="Allocate and assign a new event structure, ready to be added.">event_new()</a> and <a class="el" href="event_8h.html#a1f326019b65d319b2221b7e57d56c273" title="Deallocate a struct event * returned by event_new().">event_free()</a> instead.</p>
<p>A slightly harder way to future-proof your code is to use <a class="el" href="event_8h.html#a0f93db0db7e74f9ae173e1766415dd56" title="Return the size of struct event that the Libevent library was compiled with.">event_get_struct_event_size()</a> to determine the required size of an event at runtime.</p>
<p>Note that it is NOT safe to call this function on an event that is active or pending. Doing so WILL corrupt internal data structures in Libevent, and lead to strange, hard-to-diagnose bugs. You <em>can</em> use event_assign to change an existing event, but only if it is not active or pending!</p>
<p>The arguments for this function, and the behavior of the events that it makes, are as for <a class="el" href="event_8h.html#a6cd300e5cd15601c5e4570b221b20397" title="Allocate and assign a new event structure, ready to be added.">event_new()</a>.</p>
