\begin{Name}{3}{unw\_is\_fpreg}{David Mosberger-Tang}{Programming Library}{unw\_is\_fpreg}unw\_is\_fpreg -- check if a register is a floating-point register
\end{Name}

\section{Synopsis}

\File{\#include $<$libunwind.h$>$}\\

\Type{int} \Func{unw\_is\_fpreg}(\Type{unw\_regnum\_t} \Var{reg});\\

\section{Description}

The \Func{unw\_is\_fpreg}() routine checks whether register number
\Var{reg} is a floating-point register.

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

\section{Return Value}

The \Func{unw\_is\_fpreg}() routine returns a non-zero value if
\Var{reg} is a floating-point register.  Otherwise, it returns a value
of 0.

\section{Thread and Signal Safety}

\Func{unw\_is\_fpreg}() is thread-safe as well as safe to use
from a signal handler.
