\section{\class{wxFileOutputStream}}\label{wxfileoutputstream}

This class represents data written to a file. There are actually
two such groups of classes: this one is based on \helpref{wxFile}{wxfile} 
whereas \helpref{wxFFileInputStream}{wxffileinputstream} is based in
the \helpref{wxFFile}{wxffile} class.

Note that \helpref{SeekO()}{wxoutputstreamseeko} 
can seek beyond the end of the stream (file) and will thus not return 
{\it wxInvalidOffset} for that.

\membersection{wxFileOutputStream::\destruct{wxFileOutputStream}}\label{wxfileoutputstreamdtor}

\func{}{\destruct{wxFileOutputStream}}{\void}

Destructor.

\membersection{wxFileOutputStream::IsOk}\label{wxfileoutputstreamisok}

\constfunc{bool}{IsOk}{\void}

Returns true if the stream is initialized and ready.
