Hi ,

How do I get the following info of a process
from kernel data structures ?

1. command line ,
2. current working directory ,
3. environment ,
4. executed command ,
5. root directory.

I know these can be obtained from the proc . But how do I get from kernel data structures ?

thanks,
sha

get the pid of the process using ps, then look in /proc/<pid>/. All that info is in there

oops, sorry, you said from kernel data structures, what do you mean?

EDIT
I guess you meant to post this in the programming forum.
You can try googling task_struct which is defined in linux/sched.h, but I don't know much about accessing the struct, it's surely easier to do it by reading from /proc

I got it . I got it from the task_struct datastructure.
