 \func{}{wxOutputStream}{\void}
 
 Creates a dummy wxOutputStream object.

-Creates an input stream using the specified stream buffer \it{sbuf}. This
-stream buffer can point to another stream.

+\membersection{wxOutputStream::Close}\label{wxoutputstreamclose}
+
+\func{bool}{Close}{\void}
+
+Closes the stream, returning {\tt false} if an error occurs. The
+stream is closed implicitly in the destructor if Close() is not
+called explicitly.
+
+If this stream wraps another stream or some other resource such
+as a file, then the underlying resource is closed too if it is owned
+by this stream, or left open otherwise.

+\constfunc{size\_t}{LastWrite}{\void}
+
+Returns the number of bytes written during the last 
+\helpref{Write()}{wxoutputstreamwrite}. It may return $0$ even if there is no
+error on the stream if it is only temporarily impossible to write to it.

+\membersection{wxOutputStream::PutC}\label{wxoutputstreamputc}
 
 \func{void}{PutC}{\param{char}{ c}}
 
 Puts the specified character in the output queue and increments the
 stream position.

-\membersection{wxOutputStream::LastWrite}
+Writes up to the specified amount of bytes using the data of {\it buffer}. Note
+that not all data can always be written so you must check the number of bytes
+really written to the stream using \helpref{LastWrite()}{wxoutputstreamlastwrite} 
+when this function returns. In some cases (for example a write end of a pipe
+which is currently full) it is even possible that there is no errors and zero
+bytes have been written.

+This function returns a reference on the current object, so the user can test

+\func{wxOutputStream\&}{Write}{\param{wxInputStream\&}{ stream\_in}}
+
+Reads data from the specified input stream and stores them
