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.
