Subject: What is ptrace flag PT_TRACESYSGOOD for?
Date: Tue, 14 Mar 2006 05:26:52 -0500 [thread overview]
Message-ID: <200603140531_MC3-1-BAA0-B3C3@compuserve.com> (raw)
I am trying to document PTRACE_SETOPTIONS and I can't figure out what
the option PTRACE_O_TRACESYSGOOD is used for. Google is no help;
I can't find an explanation for _why_ it's there. All I can see is that
it causes ptrace() to deliver syscall stops with SIGTRAP | 0x80
instead of just SIGTRAP and it can be used with PTRACE_SYSEMU.
