+\membersection{::Strlen}\label{strlen}
+
+\func{size\_t}{Strlen}{\param{const char *}{ p}}
+
+This is a safe version of standard function {\it strlen()}: it does exactly the
+same thing (i.e. returns the length of the string) except that it returns 0 if
+{\it p} is the NULL pointer.
+
+\membersection{::wxGetTranslation}\label{wxgettranslation}
+
+\func{const char *}{wxGetTranslation}{\param{const char * }{str}}
+
+This function returns the translation of string {\it str} in the current 
+\helpref{locale}{wxlocale}. If the string is not found in any of the loaded
+message catalogs (see \helpref{i18n overview}{internationalization}), the
+original string is returned. In debug build, an error message is logged - this
+should help to find the strings which were not yet translated. As this function
+is used very often, an alternative syntax is provided: the \_() macro is
+defined as wxGetTranslation().
