I'm not sure why we need to create one library for each function (!),
that sounds like bad packaging to me, but then again I'm clueless
about Mozilla framework or HTTP mobility, so maybe this is something
that's enforced by the framework.

If you want to clone a message body, then the above snippet won't do
it. Use this instead:
{
pjsip_rx_data *rdata;
pjsip_msg *msg;
char dup[1500];
int dup_len;
// retrieve rdata from pjsip_event
// see http://trac.pjsip.org/repos/wiki/FAQ#pjsip_event
rdata = ...
msg = rdata->msg_info.msg;
// extract text representation of message body to "dup"
dup_len = pjsip_print_text_body(msg->body, dup, sizeof(dup));
}
I'm not sure who are your supposed to communicate the cloned body to
another XPCOM or whatever mechanism that you use, so I can't comment
on your snippet below. But lets start with having correct message body
content by using my snippet above first.
