Not at all! I'm talking about tracing the kernel calls it's making.
Depending on your platform, the tool for this is called strace,
ktrace, truss, or maybe even just trace. With strace you'd do
something like
strace -p PID-of-process 2>outfile
... wait 30 sec or so ...
control-C
Not sure about the APIs for the others but they're probably roughly
similar ... read the man page ...
