unw_regname - Man Page

#include <libunwind.h>

const char *unw_regname(unw_regnum_t regnum);

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.

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