11 int unw_is_fpreg(unw_regnum_t reg);
12
14 The unw_is_fpreg() routine checks whether register number reg is a
15 floating-point register.
16
17 This routine is normally implemented as a macro and applications should
18 not attempt to take its address.
19
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
25 unw_is_fpreg() is thread-safe as well as safe to use from a signal han‐
26 dler.
