Hi
I am trying to read the stack size from user area for processes which I am ptracing, for some reason the stack is being reported as ffffffff.
This is how I am trying read the stack size, using struct user from sys/user.h, I am on x86,
stack_size = ptrace (PTRACE_PEEKUSER, getpid(), offsetof (struct user, u_ssize), 0);
Any idea? What is the best way to read stack size of each thread? I know getrlimit() but that just talks about size of main thread. Each thread on my system can have different stack size and I cant use pthread_* functions here.
-Leo.
