Hi,
I'm trying to use libunwind to get the stack trace for a different
process (by doing a ptrace(PTRACE_ATTACH...)). And I'm doing
a ptrace(PTRACE_DETACH, ...) to let the "remote" process
continue. It works okay as long everything is normal. But I noticed
in some cases unw_init_remote fails, and even though I do a
ptrace(PTRACE_DETACH ...) from the remote process, the remote
process still seems stuck.
I'm wondering if I'm using the right approach, or if there is a problem
with my use of libunwind. Any help is appreciated.
- Thanks,
- Rao.
