-\func{}{wxOutputStream}{\param{wxStreamBuffer*}{ sbuf}}

+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

-Writes the specified amount of bytes using the data of \it{buffer}. 
-\it{WARNING!} The buffer absolutely needs to have at least the specified size.
+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
 any states of the stream right away.
