Hi,
How can get the environment variables accessed during a execve call?
I could not find any information with respect to that.
I would like to know which environment variables are used when executing a
certain command line.
Thanks!

There is the env_var() function to access individual environment variables.
See http://sourceware.org/systemtap/tapsets/API-env-var.html
You might want to look at the code in the context-envvar.stp tapset to see
how to get at other information.
Cheers,
Mark
