\section{CENUM Lookup Enumerated C Type}

\subsection{Usage}

The \verb|cenum| function allows you to use the textual strings of C 
enumerated types (that have been defined using \verb|ctypedefine|) in
your FreeMat scripts isntead of the hardcoded numerical values.  The
general syntax for its use is
\begin{verbatim}
  enum_int = cenum(enum_type,enum_string)
\end{verbatim}
which looks up the integer value of the enumerated type based on the
string.  You can also supply an integer argument, in which case
\verb|cenum| will find the matching string
\begin{verbatim}
  enum_string = cenum(enum_type,enum_int)
\end{verbatim}
