And what > meaning of the "argstr"? 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. > 2. how use systemtap probes the watchpoint?

If not, please try to rephrase your question. Josh Stone
