Which one to use Cross Memory Attach or ptrace?
Clash Royale CLAN TAG#URR8PPP

I'm trying out ptrace system calls, I just discovered Cross Memory Attach from Christopher Yeoh.
I wonder which one is better in term of performance between Cross Memory Attach and ptrace.
Thanks in advance

use both -- they're not equivalent. use ptrace() to control the process and process_vm_*() instead of PTRACE_PEEK or POKE.

you can also use/proc/PID/mem, but since there's no multi-pread() or multi-pwrite(), the process_vm_*() funcs are nicer, even if the rationale for their existence is not convincing ;-)

Thank you very much @mosvy, why process_vm_*() is nicer for read & write than ptrace with PEEK and POKE please ? :)

I was saying that process_vm_*() are nicer than pread, pwrite, readv, etc on /proc/pid/mem. Their advantage vs ptrace_peekdata or pokedata is obvious -- the latter can only transfer one word at a time. I suggest you try them insyead of doing a dry assessment.
