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

#include <libunwind.h>

int unw_is_fpreg(unw_regnum_t reg);

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.

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