       unw_is_fpreg -- check if a register is a floating-point register

SYNOPSIS

       #include <libunwind.h>

       int unw_is_fpreg(unw_regnum_t reg);

DESCRIPTION

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

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

       The  unw_is_fpreg()  routine returns a non-zero value if reg is a floating-point register.
       Otherwise, it returns a value of 0.

THREAD AND SIGNAL SAFETY

       unw_is_fpreg() is thread-safe as well as safe to use from a signal handler.
