  27 Initializes a new read-only memory stream which will use the specified buffer
  28 {\it data} of length {\it len}. The stream does not take ownership of the
  29 buffer, i.e. that it will not delete in its destructor.

  61 \func{}{wxMemoryOutputStream}{\param{char *}{ data = NULL}, \param{size\_t}{ length = 0}}
  62
  63 If {\it data} is NULL, then it will initialize a new empty buffer which will
  64 grow if required.
  65
  66 \wxheading{Warning}
  67
  68 If the buffer is created, it will be destroyed at the destruction of the
  69 stream.

  80
  81 CopyTo allowed you to transfer data from the internal buffer of
  82 wxMemoryOutputStream to an external buffer. {\it len} specifies the size of
  83 the buffer.
  84
  85 \wxheading{Returned value}
  86
  87 CopyTo returns the number of bytes copied to the buffer. Generally it is either
  88 len or the size of the stream buffer.
