+\section{\class{wxStringBuffer}}\label{wxstringbuffer}
+
+This tiny class allows to conveniently access the \helpref{wxString}{wxstring} 
+internal buffer as a writable pointer without any risk to forget to restore
+the string to the usable state later.
+
+For example, assuming you have a low-level OS function called 
+{\tt GetMeaningOfLifeAsString(char *)} returning the value in the provided
+buffer (which must be writable, of course) you might call it like this:
+
+\begin{verbatim}
+    wxString theAnswer;
+    GetMeaningOfLifeAsString(wxStringBuffer(theAnswer, 1024));
