Hi all I try to use libunwind (on arm linux) and I need a clarification.
I use libunwind to get call stacks of a running multithreaded process. Do I need to call 'UPT_create' for each thread pid, as the documentation of unw_init_remote() seems to imply, or only once for the process pid ? I looked at libunwind sources and /proc on my current linux machine, and see that 'maps_init' in src/os-linux.h opens /proc/pid/maps, while on my machine that file exists only with the pid of a process, but not for any of its threads, so _UPT_get_proc_info, as called by unw_step often fails, IIRC. Do I need to create my own find_proc_info accessor that will call _UPT_find_proc_info replacing the thread (void *arg) by one created for the process ? Is there a remote-multithreaded version of the show_backtrace example in libunwind(3) man page ?
