You can create a similar stream by this way:<P>
<PRE>
wxStreamBuffer *sb = new wxStreamBuffer(wxStreamBuffer::write);
wxOutputStream *input = new wxOutputStream(sb);
// If there are data
sb->SetBufferIO(data, data\_end);
// Else
sb->Fixed(FALSE);
</PRE>
This way is also useful to create read/write memory stream:<P>
<PRE>
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);
</PRE>

If <I>data</I> is NULL, then it will initialize a new empty buffer which will
grow when it needs.<P>
<B><FONT COLOR="#FF0000">Warning</FONT></B><P>
If the buffer is created, it will be destroyed at the destruction of the
stream.<P>
