\membersection{wxStreamBase::wxStreamBase}
\func{}{wxStreamBase}{\void}
Creates a dummy stream object. It doesn't do anything.
\membersection{wxStreamBase::\destruct{wxStreamBase}}
\func{}{\destruct{wxStreamBase}}{\void}
Destructor.
\membersection{wxStreamBase::LastError}\label{wxstreambaselasterror}
\constfunc{wxStreamError}{LastError}{\void}
This function returns the last error.
\twocolwidtha{5cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf wxStream_NOERROR}}{No error occured.}
\twocolitem{{\bf wxStream_EOF}}{An End-Of-File occured.}
\twocolitem{{\bf wxStream_WRITE_ERR}}{A generic error occured on the last write call.}
\twocolitem{{\bf wxStream_READ_ERR}}{A generic error occured on the last read call.}
\end{twocollist}
\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::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
real position in the stream.
\membersection{wxStreamBase::OnSysWrite}
\func{size\_t}{OnSysWrite}{\param{void *}{buffer}, \param{size\_t}{ bufsize}}
See \helpref{OnSysRead}{wxstreambaseonsysread}.
\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).
\wxheading{Warning}
There are streams which do not have size by definition, such as socket streams.
In that cases, StreamSize returns an invalid size represented by
\begin{verbatim}
~(size_t)0
\end{verbatim}
