       The   _U_dyn_register()  routine  registers  unwind-info  for  a  dynamically  generated  procedure.  The
       procedure's unwind-info is described by a structure of type unw_dyn_info_t (see libunwind-dynamic(3)).  A
       pointer to this structure is passed in argument di.

       The _U_dyn_register() routine is guaranteed to execute in constant time (in  the  absence  of  contention
       from concurrent calls to _U_dyn_register() or _U_dyn_cancel()).

libunwind-dynamic(3), _U_dyn_cancel(3)

       #include <libunwind.h>

       void _U_dyn_register(unw_dyn_info_t *di);

       _U_dyn_register() is thread-safe but not safe to use from a signal handler.
