Subject: observe & control thread state for exit futex ?
Date: Sun, 13 Apr 2003 19:52:08 -0700 [thread overview]
Message-ID: <3E9A2258.9020507@BitWagon.com> (raw)
How can a debugger, newly attached to an arbitrary thread, determine whether
the thread has a pending exit futex and associated memory location to clear
[CLONE_CHILD_CLEARTID flag and child_tid_ptr parameter at __clone()]?
If so, then how can the debugger determine the address, change the address,
cancel the futex, and/or intercept the notification?
