In your script, argstr has not been set to anything. It is being
inferred as a string from the format you gave, and the default value of
a string is "". If instead you use the syscall tapset to probe
syscall.open, then a formatted argstr will be built for you. The argstr
gives a string representation of all of the parameters to the syscall.

I'm not sure what you're asking here. The SystemTap website has a few
architecture documents that might give the answer you're looking for.
If not, please try to rephrase your question.
