What behavior would you expect from this sequence of commands?
ktrace -tw -p 1234
ktrace -c -p 1234
Based on this...
-c Clear the trace points associated with the specified file
...I would expect the second command to clear the trace point for
context switches. It doesn't. I have to specify -tw with the -c to get
that behavior. This makes sense; it's just not what I was expecting.
Assuming we want to keep this behavior, can we clarify the -c flag in
man page? I would suggest:
If the -t flag is not specified, clear the default set of trace points.
