Try to declare the second argument 'pj_timer_entry entry' in a global scope.

Benny yesterday you told me:

I has been trying to understand this function and how to use it bu I can?t make ir work fine. I use:
pjsip_endpt_schedule_timer (pjsua_get_pjsip_endpt(),
my_timer_entry,
my_timer);
- The first argument of this function is the pjsip endpoint. So, I think "pjsua_get_pjsip_endpt()" is right here. Isn't it?
- The second argument must be a timer_entry pointer, so I define:
struct pj_timer_entry* my_timer_entry;
my_timer_entry->id = 1;
my_timer_entry->cb = &funcion_aux;
my_timer_entry->_timer_value = my_timer_2; //I don't know the objective of this timer.
Where :
struct pj_time_val my_timer_2;
my_timer_2.sec = 5; my_timer_2.msec=0;
static void funcion_aux( pj_timer_heap_t *timer_heap,
struct pj_timer_entry *entry)
{
PJ_UNUSED_ARG(timer_heap);
PJ_UNUSED_ARG(entry);
puts("MINE ----> Periodic call");
}
Is this right for the second argument?
- The third argument must be a time_val pointer, so I use:
struct pj_time_val* my_timer;
my_timer->sec=5; my_timer->msec=0;
I don't know why it doesn't work. I think this code should make my application to show the message "MINE---> Periodic call" every 5 seconds but it doesn't do it.
Where am I wrong?
Thanks a lot, and sorry for the large mail.
