+\func{}{wxCONCAT}{\param{}{x}, \param{}{y}}
+
+This macro returns the concatenation of two tokens \arg{x} and \arg{y}.
+
+
+\membersection{wxDYNLIB\_FUNCTION}\label{wxdynlibfunction}
+
+\func{}{wxDYNLIB\_FUNCTION}{\param{}{type}, \param{}{name}, \param{}{dynlib}}
+
+When loading a function from a DLL you always have to cast the returned
+{\tt void *} pointer to the correct type and, even more annoyingly, you have to
+repeat this type twice if you want to declare and define a function pointer all
+in one line
+
+This macro makes this slightly less painful by allowing you to specify the
+type only once, as the first parameter, and creating a variable of this type
+named after the function but with {\tt pfn} prefix and initialized with the
+function \arg{name} from the \helpref{wxDynamicLibrary}{wxdynamiclibrary}
+\arg{dynlib}.
+
+\wxheading{Parameters}
+
+\docparam{type}{the type of the function}
+
+\docparam{name}{the name of the function to load, not a string (without quotes,
+it is quoted automatically by the macro)}
+
+\docparam{dynlib}{the library to load the function from}
+
+
+
+\membersection{wxDEPRECATED}\label{wxdeprecated}
+
+This macro can be used around a function declaration to generate warnings
+indicating that this function is deprecated (i.e. obsolete and planned to be
+removed in the future) when it is used. Only Visual C++ 7 and higher and g++
+compilers currently support this functionality.
+
+Example of use:
+\begin{verbatim}
+ // old function, use wxString version instead
+ wxDEPRECATED( void wxGetSomething(char *buf, size_t len) );
+
+ // ...
+ wxString wxGetSomething();
+\end{verbatim}
+
+
+\membersection{wxDEPRECATED\_BUT\_USED\_INTERNALLY}\label{wxdeprecatedbutusedinternally}
+
+This is a special version of \helpref{wxDEPRECATED}{wxdeprecated} macro which
+only does something when the deprecated function is used from the code outside
+wxWidgets itself but doesn't generate warnings when it is used from wxWidgets.
+It is used with the virtual functions which are called by the library itself --
+even if such function is deprecated the library still has to call it to ensure
+that the existing code overriding it continues to work, but the use of this
+macro ensures that a deprecation warning will be generated if this function is
+used from the user code or, in case of Visual C++, even when it is simply
+overridden.
