Oh, yes, one could in fact argue that libc is broken. It doesn't
handle the PTRACE_PEEK*_3264 commands specially, as it does with
PTRACE_PEEK*. So you'd have to write
if (cmd == *_3264)
ptrace (cmd, tid, addr, buf)
else
*buf = ptrace (cmd, tid, addr, 0);
... and then rely on libc never being fixed. And in this case I
don't see what going through libc buys us besides frustration.
