Replying to myself in hope that it helps someone else and for posterity.
I think I fixed my issue. I used su_root_step in my thread loop instead
of su_root_run. So now my pseudo code looks like:
AppSingleton *myapp;
su_init()
su_home_t *tmp
tmp = su_home_new()
myapp->home = tmp;
su_home_init(myapp->home)
myapp->root = su_root_osx_runloop_create(*myapp)
nua_create(...)
su_root_release(myapp->root)
pthread_create(thread,NULL,root_thread,NULL)
void root_thread() {
AppSingleton *myapp;
su_root_obtain(myapp->root);
su_root_osx_prepare_run(myapp->root);
while (1) {
su_root_step(myapp->root, 20);
}
su_root_release)(myapp->root);
}
If anyone sees an issue with running the event loop in this fashion,
please advise me. I'd like to write it in the proper fashion, but this
works and does what I want.
Thanks,
Andy.
