This class implements an output stream which writes data either to a
user-provided or internally allocated string. Note that currently this stream

Otherwise, an internal string is used for the data written to this stream, use
\helpref{GetString()}{wxstringoutputstreamgetstring} to get access to it.
+If \arg{str} is used, data written to the stream is appended to the current
+contents of it, i.e. the string is not cleared here. However if it is not
+empty, the positions returned by \helpref{TellO}{wxoutputstreamtello} will be
+offset by the initial string length, i.e. initial stream position will be the
+initial length of the string and not $0$.
