\membersection{wxOutputStream::wxOutputStream}
\func{}{wxOutputStream}{\void}
Creates a dummy wxOutputStream object.
+
\membersection{wxOutputStream::\destruct{wxOutputStream}}
\func{}{\destruct{wxOutputStream}}{\void}
Destructor.
-\membersection{wxOutputStream::LastWrite}
+
+\membersection{wxOutputStream::LastWrite}\label{wxoutputstreamlastwrite}
\constfunc{size\_t}{LastWrite}{\void}
-Returns the number of bytes written during the last Write().
+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}
Puts the specified character in the output queue and increments the
stream position.
-\membersection{wxOutputStream::SeekO}
-\func{off\_t}{SeekO}{\param{off\_t}{ pos}, \param{wxSeekMode}{ mode}}
+\membersection{wxOutputStream::SeekO}\label{wxoutputstreamseeko}
+
+\func{off\_t}{SeekO}{\param{off\_t}{ pos}, \param{wxSeekMode}{ mode = wxFromStart}}
Changes the stream current position.
+\wxheading{Parameters}
+
+\docparam{pos}{Offset to seek to.}
+
+\docparam{mode}{One of {\bf wxFromStart}, {\bf wxFromEnd}, {\bf wxFromCurrent}.}
+
+\wxheading{Return value}
+
+The new stream position or wxInvalidOffset on error.
+
+
\membersection{wxOutputStream::TellO}
\constfunc{off\_t}{TellO}{\void}
Returns the current stream position.
-\membersection{wxOutputStream::Write}

+\membersection{wxOutputStream::Write}\label{wxoutputstreamwrite}
\func{wxOutputStream\&}{Write}{\param{const void *}{buffer}, \param{size\_t}{ size}}
-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.
