\membersection{wxStreamBase::wxStreamBase}

\func{}{wxStreamBase}{\void}

Creates a dummy stream object.

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

\func{}{\destruct{wxStreamBase}}{\void}

Destructor.

\membersection{wxStreamBase::LastError}\label{wxstreambaselasterror}

\constfunc{wxStreamError}{LastError}{\void}

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

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

This function returns the size of the stream. For example, for a file it is the size of
the file). Warning! There are streams which do not have size by definition, such as 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 that 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.
