Hey Paulo,
Thanks for clearing the basic concepts. In your second
point you say "different callback for different method". Can't I use a
single callback and using switch case do the function calling. Could you
please explain.
I am using NUA now. But when I send a SUBSCRIBE message to the server I get
two 401 Unauthorize, I couldn't make out why I am having this problem. I
would be thankful to you, if you have a look on my code and make out what's
the problem.
Thanks for clearing my doubts,
Mayur
Hello,
I took a look at your code and I noticed that (1) you call su_root_run()
several times and breaks it. su_root_run() is supposed to be called only
once and the loop should be broken (by calling su_root_break()) only when
you want to exit your app.
(2) You can call a request method inside the callback. Once you're
inside the callback, you must not worry about the event loop, because it is
already running (this is why your second call to su_root_run() won't work).
You should provide a different callback for a specific method or provide
some information through the magic pointer so that your app keeps track of
calls' states.
(3) Have you considered using NUA instead of NTA? There are a lot of
things that NUA will handle automatically that NTA won't. If you really need
NTA, authentication is nothing but, to respond to the challenge with the
correct hash. You may need to search for any library to calculate the MD5
authorization digests or build your own. <

Paulo.
