\section{\class{wxDynamicLibrary}}\label{wxdynamiclibrary}
this class to load a library and don't worry about unloading it -- it will be
done in the objects destructor automatically.

+\func{static wxString}{CanonicalizeName}{\param{const wxString\& }{name}, \param{wxDynamicLibraryCategory}{ cat = wxDL\_LIBRARY}}
Returns the platform-specific full name for the library called \arg{name}. E.g.
it adds a {\tt ".dll"} extension under Windows and {\tt "lib"} prefix and

+\func{static wxString}{CanonicalizePluginName}{\param{const wxString\& }{name}, \param{wxPluginCategory}{ cat = wxDL\_PLUGIN\_GUI}}
This function does the same thing as
\helpref{CanonicalizeName}{wxdynamiclibrarycanonicalizename} but for wxWidgets
Detaches this object from its library handle, i.e. the object will not unload
the library any longer in its destructor but it is now the callers

+\membersection{wxDynamicLibrary::GetSymbolAorW}\label{wxdynamiclibrarygetsymbolaorw}
+
+\constfunc{void *}{GetSymbolAorW}{\param{const wxString\& }{name}}
+
+This function is available only under Windows as it is only useful when
+dynamically loading symbols from standard Windows DLLs. Such functions have
+either \texttt{'A'} (in ANSI build) or \texttt{'W'} (in Unicode, or wide
+character build) suffix if they take string parameters. Using this function you
+can use just the base name of the function and the correct suffix is appende
+automatically depending on the current build. Otherwise, this method is
+identical to \helpref{GetSymbol}{wxdynamiclibrarygetsymbol}.
+
+
+\membersection{wxDynamicLibrary::GetProgramHandle}\label{wxdynamiclibrarygetprogramhandle}
+
+\func{static wxDllType}{GetProgramHandle}{\void}
+
+Return a valid handle for the main program itself or \texttt{NULL} if symbols
+from the main program can't be loaded on this platform.
+
+
\membersection{wxDynamicLibrary::HasSymbol}\label{wxdynamiclibraryhassymbol}
\constfunc{bool}{HasSymbol}{\param{const wxString\& }{name}}
Returns \true if the library was successfully loaded, \false otherwise.
+\membersection{wxDynamicLibrary::ListLoaded}\label{wxdynamiclibrarylistloaded}
+
+\func{static wxDynamicLibraryDetailsArray}{ListLoaded}{\void}
+
+This static method returns an \helpref{array}{wxarray} containing the details
+of all modules loaded into the address space of the current project, the array
+elements are object of \texttt{wxDynamicLibraryDetails} class. The array will
+be empty if an error occurred.
+
+This method is currently implemented only under Win32 and Linux and is useful
+mostly for diagnostics purposes.
+
+
\membersection{wxDynamicLibrary::Load}\label{wxdynamiclibraryload}
\func{bool}{Load}{\param{const wxString\& }{name}, \param{int }{flags = wxDL\_DEFAULT}}
\twocolitem{wxDL\_GLOBAL}{equivalent of RTLD\_GLOBAL under Unix, ignored elsewhere}
\twocolitem{wxDL\_VERBATIM}{don't try to append the appropriate extension to
the library name (this is done by default).}
+\twocolitem{wxDL\_DEFAULT}{default flags, same as wxDL\_NOW currently}
\end{twocollist}
Returns \true if the library was successfully loaded, \false otherwise.
In this case you may call \helpref{Detach}{wxdynamiclibrarydetach} and store
the handle somewhere and call this static method later to unload it.

+\section{\class{wxDynamicLibraryDetails}}\label{wxdynamiclibrarydetails}
+
+This class is used for the objects returned by
+\helpref{wxDynamicLibrary::ListLoaded}{wxdynamiclibrarylistloaded} method and
+contains the information about a single module loaded into the address space of
+the current process. A module in this context may be either a dynamic library
+or the main program itself.

+
+\membersection{wxDynamicLibraryDetails::GetName}\label{wxdynamiclibrarygetname}
+
+\constfunc{wxString}{GetName}{\void}
+
+Returns the base name of this module, e.g. \texttt{kernel32.dll} or
+\texttt{libc-2.3.2.so}.
+
+
+\membersection{wxDynamicLibraryDetails::GetPath}\label{wxdynamiclibrarygetpath}
+
+\constfunc{wxString}{GetPath}{\void}
+
+Returns the full path of this module if available, e.g.
+\texttt{c:$\backslash$windows$\backslash$system32$\backslash$kernel32.dll} or
+\texttt{/lib/libc-2.3.2.so}.
+
+
+\membersection{wxDynamicLibraryDetails::GetAddress}\label{wxdynamiclibrarygetaddress}
+
+\constfunc{bool}{GetAddress}{\param{void **}{addr}, \param{size\_t }{*len}}
+
+Retrieves the load address and the size of this module.
+
+\wxheading{Parameters}
+
+\docparam{addr}{the pointer to the location to return load address in, may be
+\texttt{NULL}}
+
+\docparam{len}{pointer to the location to return the size of this module in
+memory in, may be \texttt{NULL}}
+
+\wxheading{Return value}
+
+\true if the load address and module size were retrieved, \false if this
+information is not available.
+
+
+\membersection{wxDynamicLibraryDetails::GetVersion}\label{wxdynamiclibrarygetversion}
+
+\constfunc{wxString}{GetVersion}{\void}
+
+Returns the version of this module, e.g. \texttt{5.2.3790.0} or
+\texttt{2.3.2}. The returned string is empty if the version information is not
+available.
