\membersection{wxStreamBase::wxStreamBase}
\func{}{wxStreamBase}{\void}

Creates a dummy stream object.

\membersection{wxStreamBase::\destruct{wxStreamBase}}
\func{}{\destruct{wxStreamBase}}

Destructor.

\membersection{wxStreamBase::LastError}
\constfunc{wxStreamError}{LastError}{\void}

This function returns the last happened error. It is of the form:
% TODOTODOTODOTODOTODOTODOTODO

\membersection{wxStreamBase::StreamSize}
\constfunc{size_t}{StreamSize}{\void}

This function returns the size of the stream. (E.g. for a file it the size of
the file) Warning ! There are streams which haven't size by definition (E.g.
a socket).

\membersection{wxStreamBase::OnSysRead}\label{wxstreambaseonsysread}
\func{size_t}{OnSysRead}{\param{void *}{buffer}, \param{size_t}{ bufsize}}

Internal function. It is called when the stream buffer needs a buffer of the
specified size. It should return the size which was actually read.

\membersection{wxStreamBase::OnSysWrite}
\func{size_t}{OnSysWrite}{\param{void *}{buffer}, \param{size_t}{ bufsize}}

See \helpref{OnSysRead}{wxstreambaseonsysread}.

\membersection{wxStreamBase::OnSysSeek}
\func{off_t}{OnSysSeek}{\param{off_t}{ pos}, \param{wxSeekMode}{ mode}}

Internal function. It is called when the stream buffer needs to change the
current position in the stream. See \helpref{wxStreamBuffer::Seek}{wxstreambufferseek}

\membersection{wxStreamBase::OnSysTell}
\constfunc{off_t}{OnSysTell}{\void}

Internal function. Is is called when the stream buffer needs to know the
current position in the stream.

\membersection{wxInputStream::wxInputStream}
\func{}{wxInputStream}{\void}

Creates a dummy input stream.

\func{}{wxInputStream}{\param{wxStreamBuffer *}{sbuf}}

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

\membersection{wxInputStream::\destruct{wxInputStream}}
\func{}{\destruct{wxInputStream}}

Destructor.

% -----------
% IO function

\membersection{wxInputStream::Peek}
\func{char}{Peek}{\void}

Returns the first character in the input queue without removing it.

\membersection{wxInputStream::GetC}
\func{char}{GetC}{\void}

Returns the first character in the input queue and removes it.

\membersection{wxInputStream::Read}
\func{wxInputStream&}{Read}{\param{void *}{buffer}, \param{size_t}{ size}}

Reads the specified amount of bytes and stores the data in \it{buffer}.
\it{WARNING !} The buffer needs absolutely to have at least the specified size.

This function returns a reference on the current object, so the user can test
any states of the stream right away.

\func{wxInputStream&}{Read}{\param{wxOutputStream&}{ stream_out}}

Reads data from the input queue and stores them in the specified output stream.
The data is read until an error is raised by one of the two streams.

% ------------------
% Position functions
% ------------------

\membersection{wxInputStream::SeekI}
\func{off_t}{SeekI}{\param{off_t}{ pos}, \param{wxSeekMode}{ mode = wxFromStart}}

Changes the stream current position.

\membersection{wxInputStream::TellI}
\constfunc{off_t}{TellI}{\void}

Returns the current stream position.

% ---------------
% State functions
% ---------------

\membersection{wxInputStream::InputStreamBuffer}
\func{wxStreamBuffer *}{InputStreamBuffer}{\void}

Returns the stream buffer associated with the input stream.

\membersection{wxInputStream::LastRead}
\constfunc{size_t}{LastRead}{\void}

Returns the last amount of bytes read.

\membersection{wxOutputStream::wxOutputStream}
\func{}{wxOutputStream}{\void}

Creates a dummy wxOutputStream object.

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

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

\membersection{wxOutputStream::\destruct{wxOutputStream}}
\func{}{\destruct{wxOutputStream}}

Destructor.

% -----------
% IO function

\membersection{wxOutputStream::PutC}
\func{void}{PutC}{\param{char}{ c}}

Puts the specified character in the output queue and increments the
stream position.

\membersection{wxOutputStream::Write}
\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 needs absolutely to have at least the specified size.

This function returns a reference on the current object, so the user can test
any states of the stream right away.

\func{wxOutputStream&}{Write}{\param{wxInputStream&}{ stream_in}}

Reads data from the specified input stream and stores them 
in the current stream. The data is read until an error is raised
by one of the two streams.

% ------------------
% Position functions
% ------------------

\membersection{wxOutputStream::SeekO}
\func{off_t}{SeekO}{\param{off_t}{ pos}, \param{wxSeekMode}}
