		GHashTable *	handlers
	)

Initialize the event handlers broadcaster.

Parameters

[in]	enabled	Whether broadcasting events should be supported at all
[in]	server_name	The name of this server, to be added to all events
[in]	handlers	Map of all registered event handlers

Returns

0 on success, a negative integer otherwise

janus_events_is_enabled()

gboolean janus_events_is_enabled

(

void
