UNW_REGNAME(3)						       Programming Library						    UNW_REGNAME(3)

NAME
       unw_regname -- get register name

SYNOPSIS
       #include <libunwind.h>

       const char *unw_regname(unw_regnum_t regnum);

DESCRIPTION
       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.

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

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