\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}. The stream does not take ownership of the
buffer, i.e. that it will not delete in its destructor.
\membersection{wxMemoryInputStream::\destruct{wxMemoryInputStream}}
\func{}{\destruct{wxMemoryInputStream}}{\void}
Destructor.

\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 if required.
\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.
\membersection{wxMemoryOutputStream::CopyTo}
\constfunc{size\_t}{CopyTo}{\param{char *}{buffer}, \param{size\_t }{len}}
CopyTo allowed you to transfer data from the internal buffer of
wxMemoryOutputStream to an external buffer. {\it len} specifies the size of
the buffer.
\wxheading{Returned value}
CopyTo returns the number of bytes copied to the buffer. Generally it is either
len or the size of the stream buffer.
