relay channel question

I am trying to write binary output to the relay channel and am wondering 
how to write a 32-bit integer?  _stp_print_binary only seems to deal 
with 64 bit ints.

How does systemtap separate the relay channel output on a per-cpu 
basis?  Does it just use the currently active CPU that is making the 
write request and put its output in the relay buffer for that CPU?  Is 
there any way to write to a CPU specific relay buffer?   I think  I will 
need this to write  header information for each CPU but there would only 
be one active CPU that is doing all of these writes.
