\section{\class{wxFFileInputStream}}\label{wxffileinputstream}

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

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

\membersection{wxFFileInputStream::wxFFileInputStream}\label{wxffileinputstreamctor}

\func{}{wxFFileInputStream}{\param{const wxString\&}{ filename}, \param{const wxChar *}{ mode = "rb"}}

Opens the specified file using its {\it filename} name using the specified mode.

\func{}{wxFFileInputStream}{\param{wxFFile\&}{ file}}

Initializes a file stream in read-only mode using the file I/O object {\it file}.

\func{}{wxFFileInputStream}{\param{FILE *}{ fp}}

Initializes a file stream in read-only mode using the specified file pointer {\it fp}.

\membersection{wxFFileInputStream::\destruct{wxFFileInputStream}}\label{wxffileinputstreamdtor}

\func{}{\destruct{wxFFileInputStream}}{\void}

Destructor.

\membersection{wxFFileInputStream::Ok}\label{wxffileinputstreamok}

\constfunc{bool}{Ok}{\void}

Returns true if the stream is initialized and ready.

\section{\class{wxFFileOutputStream}}\label{wxffileoutputstream}

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

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