Hi Benny and All,
I have suffered a problem in these days.
When there incoming a subscribe, The on_new_transaction() will be called to create dialog sub list.
dlgsub_head = (struct dlgsub*) dlg->mod_data[mod_evsub.mod.id];
if (dlgsub_head == NULL)
{
// allocate a new dlgsub instance
}
// Point to the first dlgsub in the list..
dlgsub = dlgsub_head->next;
However, we have the following problem..
Please correct me in case of my missunderstand, thanks!
(1) Where the dlg->mod_data[mod_evsub.mod.id] was initialized?
pjsip_dlg_add_usage is the one who initial the dlg->mod_data.
Is that correct?
(2) We found if multiple subscribes were received, the last one will overwrite the previous one in the dlgsub list.
My question was should we allocate a new node once the dlgsub not NULL
dlgsub_head = (struct dlgsub*) dlg->mod_data[mod_evsub.mod.id];
if (dlgsub_head == NULL) {
// allocate new node
}
else
// Allocate new node and attach to the existed list
