\section{\product{Dynload} C library API}

The \product{dynload} library encapsulates dynamic loading mechanisms and
gives access to functions in foreign dynamic libraries and code modules.

\subsection{Loading code}

\begin{lstlisting}[language=c,label=dl-load]
void* dlLoadLibrary(const char* libpath);
void  dlFreeLibrary(void* libhandle);
\end{lstlisting}

\lstinline{dlLoadLibrary} loads a dynamic library at \lstinline{libpath}
and returns a handle to it for use in \lstinline{dlFreeLibrary} and
\lstinline{dlFindSymbol} calls.

\lstinline{dlFreeLibrary} frees the loaded library with handle \lstinline{pLib}.

\subsection{Retrieving functions}

\begin{lstlisting}[language=c]
void* dlFindSymbol(void* libhandle, const char* symbol);
\end{lstlisting}

returns a pointer to a symbol with name \lstinline{pSymbolName} in the
library with handle \lstinline{pLib}, or returns a null pointer if the symbol cannot
be found.
