Ok Mathias, but I don't understand how to use it. In fact, imagine I ( 
i at gabber) have a session opened... the current "sess" in c2s.c, 
c2s_client_sx_callback. I 'm gonna send a packet to you ( you at gabber ), 
juste before the sm_packet.  the full jid of the session "sess" is mine, 
i at gabber. If I sent a message to you, I should be able to read somewhere 
( in nad I suppose ) that this message is for "you at gabber", no ?

 How should I call nad_find_attr  to do what I want ? I've tried 
something like :

attr_tmp = nad_find_attr(nad,0,-1,"to",NULL);    // here value is '-1'
recipient = (char*) malloc(sizeof(char) * NAD_AVAL_T(nad, attr_tmp);
recipient = (char*)NAD_AVAL(nad, attr_tmp);   // crash, due to 
attr_tmp's value

due to attr_tmp which value's -1; nad_find_attr didn't find the 
attribute "to". Moreover, this attribute value isn't "you at gabber" but 
just "gabber"... so only the domain. I saw this by using  tcpdump.
