FreeBSD provides the ptrace system call for controlling and

An alternative to the ptrace system call is the /proc filesystem.

The functionality provided by the /proc filesystem is the same as
that provided by ptrace; if differs only in its interface.

Are there having a better method or other method?

They both suck, for different reasons. In theory, ptrace sucks less
than proc, but it lacks some of proc's functionality, and fixing that
is very hard.

Would you take a little time to tell what ptrace lacks and possibly
why it is so hard, please ?

Thank you.
