Hi everyone,
I'm new in sofia sip so don't be hard on me if my questions are boring ;-)
I have to write a RTSP client/server like program using sip messages.
First of all I would like to write a server which accept connexion of
the clients and do a task switch the content of the message (which can
be XML like cc//pp or just <play/>).
I think I succeed in writing it but the client doesn't stop properly.
I got this message :
nua_destroy(0x804b4b8): FATAL: nua_shutdown not completed
client: nua.c:235: nua_destroy: Assertion `nua->nua_shutdown' failed.
Aborted
Here is my code (client) :
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sofia-sip/nua.h>

If my code doesn't permit doing what I want, what is the better mean to
do it ? sample code ?
Thanks in advance.
