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.

\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.
