+This family of macros allows to ensure that the global function \arg{func}
+with 0, 1, 2 or more parameters (up to some implementaton-defined limit) is
+executed on scope exit, whether due to a normal function return or because an
+exception has been thrown. A typical example of its usage:
+\begin{verbatim}
+    void *buf = malloc(size);
+    wxON_BLOCK_EXIT1(free, buf);
+\end{verbatim}
