+\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}.
