DESCRIPTION

14       The  unw_is_fpreg()  routine  checks  whether  register number reg is a
15       floating-point register.

17       This routine is normally implemented as a macro and applications should
18       not attempt to take its address.

RETURN VALUE

21       The  unw_is_fpreg() routine returns a non-zero value if reg is a float‐
22       ing-point register. Otherwise, it returns a value of 0.
23

THREAD AND SIGNAL SAFETY

25       unw_is_fpreg() is thread-safe as well as safe to use from a signal han‐
26       dler.
