       The  unw_regname()  routine  returns  a  printable  name for register regnum.  If regnum is an invalid or
       otherwise unrecognized register number, a string consisting of three  question  marks  is  returned.  The
       returned  string  is  statically allocated and therefore guaranteed to remain valid until the application
       terminates.

       The unw_regname() routine cannot fail and always returns a valid (non-NULL) string.

libunwind(3)

       #include <libunwind.h>

       const char *unw_regname(unw_regnum_t regnum);

       The unw_regname() routine is thread-safe as well as safe to use from a signal handler.
