\subsection{Module \texttt{LALStd.c}}

LAL replacement routines for standard C functions.  At present, this
just includes replacements for \texttt{snprintf}.

\subsection*{Prototypes}
\begin{verbatim}
int LALSnprintf( char *str, size_t size, const char *fmt, ... );
int LALVsnprintf( char *str, size_t size, const char *fmt, va_list ap );
\end{verbatim}
\idx{LALSnprintf()}
\idx{LALVsnprintf()}

\subsection*{Description}

The routines \verb+LALSnprintf()+ and \verb+LALVsnprintf()+ are
wrappers for \verb+snprintf()+ and \verb+vsnprintf()+, if these functions
are available, otherwise they are simply sprintf() or vsprintf().
It is strongly recommended that \verb+LALSnprintf()+ and \verb+LALVsnprintf()+
be used rather than \verb+sprintf()+ and \verb+vsprintf()+ as the latter are
prone to buffer-overflow problems.
