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

In your case, everything is in the process descriptor or is linked from there. /proc is an interface to kernel structures, and a very useful one. Is there a specific reason you don't want to use it? Apart from /proc you have sysctls and ioctls, which are harder to use.
