tracemem() not exactly what I had in mind
I was trying to use tracemem to look at mblk contents. First, I tried to use
mblk->b_wptr - mblk->b_rptr as the size, and was told that it had to be a
constant. Foo. (RFE #1).
Then, I tried to use 8 as the size, and kept getting decimal numbers printed.
Stumbled on #pragma D option rawbytes=true (is the =true necessary, btw?) and
that didn''t help.
Then, in desperation, I changed the size to 16. Voila!
I *think* this is because tracemem() doesn''t really look at rawbytes before it
looks for size 1, 2, 4, or 8 bytes, and handles them specially. But I''m go...

Is there way to trace memory in the dtrace ?
N_conreq:entry {
self->x=1;
calledaddr=(struct xaddrf *)arg3;
callingaddr=(struct xaddrf *)arg4;
trace(calledaddr->link_id);
tracemem(calledaddr->DTE_MAC.lsap_add, 80);
trace(callingaddr->link_id);
tracemem(callingaddr->DTE_MAC.lsap_add, 80);
}
