is used very often, an alternative syntax is provided: the \_() macro is
defined as wxGetTranslation().

\func{int}{wxSnprintf}{\param{wxChar *}{buf}, \param{size\_t }{len}, \param{const wxChar *}{format}, \param{}{...}}
This function replaces the dangerous standard function {\tt sprintf()} and is
like {\tt snprintf()} available on some platforms. The only difference with
sprintf() is that an additional argument - buffer size - is taken and the
buffer is never overflowed.
Returns the number of characters copied to the buffer or -1 if there is not
enough space.

The same as \helpref{wxSnprintf}{wxsnprintf} but takes a {\tt va\_list}
argument instead of arbitrary number of parameters.

The {\tt <wx/string.h>} header also defines \helpref{wxSnprintf}{wxsnprintf}
and \helpref{wxVsnprintf}{wxvsnprintf} functions which should be used instead
of the inherently dangerous standard {\tt sprintf()} and which use {\tt
snprintf()} instead which does buffer size checks whenever possible. Of
course, you may also use \helpref{wxString::Printf}{wxstringprintf} which is
also safe.
There is another class which might be useful when working with wxString:
\helpref{wxStringTokenizer}{wxstringtokenizer}. It is helpful when a string must
be broken into tokens and replaces the standard C library {\it
