\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}. 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.
