[Freeswitch-users] Event_handler using switch_event_bind and private user data issue

[Jon Lederman]

Hi,

 
I'm trying to set up an event handler that will send some user data to a callback function.  I am using:


 pvt = (switch_audio_weaver_t*) switch_core_session_alloc(session, sizeof(*pvt));

 if (switch_event_bind(modname, SWITCH_EVENT_CUSTOM, AUDIOWEAVER_SEND_MESSAGE, audioweaver_message_event_handler, pvt) != SWITCH_STATUS_SUCCESS) {
               switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Couldn't bind!\n");
       /* indicate that the module should continue to be loaded */
       return SWITCH_STATUS_FALSE;
}

This works fine and my event handler is called.  But, I am unclear how to get the event_user_data.  My event handler is:

static void audioweaver_message_event_handler(switch_event_t *event)
{
 switch_audio_weaver_t *pvt = (switch_audio_weaver_t *) event->event_user_data;
 switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_DEBUG, "AudioWeaver Message Event Handler Reached!");
 switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_DEBUG, switch_event_get_body(event));
  std::string reply;
  int ret = pvt->aw_talker->SendMessage("set_value,Sine1.freq,110.0", reply);

I am using mod_event_socket, which uses switch_event_fire.  I note in switch_event.h, the following:

/*!
  \brief Fire an event filling in most of the arguements with obvious values
  \param event the event to send (will be nulled on success)
  \return SWITCH_STATUS_SUCCESS if the operation was successful
  \note the body supplied by this function will supersede an existing body the event may have
*/
#define switch_event_fire(event) switch_event_fire_detailed(__FILE__, (const char * )__SWITCH_FUNC__, __LINE__, event, NULL)

/*!

How would I use switch_event_fire_detailed with mod_event_socket, which I believe is necessary in order to send the user_data?
}

However, the pointer doesn't seem to point to the private data.  Am I setting up my event handler correctly to get this data?

Thanks.
