You can create a similar stream by this way:

\begin{verbatim}
  wxStreamBuffer *sb = new wxStreamBuffer(wxStreamBuffer::read);
  wxInputStream *input = new wxInputStream(sb);

  sb->SetBufferIO(data, data\_end);
\end{verbatim}

\membersection{wxMemoryInputStream::wxMemoryInputStream}

\func{}{wxMemoryInputStream}{\param{const char *}{ data}, \param{size\_t}{ len}}

Initializes a new read-only memory stream which will use the specified buffer
\it{data} of length \it{len}.

\membersection{wxMemoryInputStream::\destruct{wxMemoryInputStream}}

\func{}{\destruct{wxFileInputStream}}{\void}

Destructor.

\helpref{wxStreamBuffer}{wxstreamBuffer}

\wxheading{Remark}

You can create a similar stream by this way:

\begin{verbatim}
  wxStreamBuffer *sb = new wxStreamBuffer(wxStreamBuffer::write);
  wxOutputStream *input = new wxOutputStream(sb);

  // If there are data
    sb->SetBufferIO(data, data\_end);
  // Else
    sb->Fixed(FALSE);
\end{verbatim}

This way is also useful to create read/write memory stream:

\begin{verbatim}
  wxStreamBuffer *sb = new wxStreamBuffer(wxStreamBuffer::read\_write);
  wxOutputStream *output = new wxOutputStream(sb);
  wxInputStream *input = new wxInputStream(sb);

  // If there are data
    sb->SetBufferIO(data, data\_end);
  // Else
    sb->Fixed(FALSE);
\end{verbatim}

\membersection{wxMemoryOutputStream::wxMemoryOutputStream}

\func{}{wxMemoryOutputStream}{\param{char *}{ data = NULL}, \param{size\_t}{ length = 0}}

If \it{data} is NULL, then it will initialize a new empty buffer which will
grow when it needs.

\wxheading{Warning}

If the buffer is created, it will be destroyed at the destruction of the
stream.

\membersection{wxMemoryOutputStream::\destruct{wxMemoryOutputStream}}

\func{}{\destruct{wxMemoryOutputStream}}{\void}

Destructor.
