Returns a pointer to the string data ({\tt const char*} in ANSI build,
{\tt const wchar\_t*} in Unicode build).
Note that the returned value is not convertible to {\tt char*} or
{\tt wchar\_t*}, use \helpref{char\_str}{wxstringcharstr} or
\helpref{wchar\_string}{wxstringwcharstr} if you need to pass string value
to a function expecting non-const pointer.

Returns an object with string data that is implicitly convertible to
{\tt char*} pointer. Note that any change to the returned buffer is lost and so
this function is only usable for passing strings to legacy libraries that
don't have const-correct API. Use \helpref{wxStringBuffer}{wxstringbuffer} if
you want to modify the string.
