% ctor & dtor
% -----------
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}}{\void}
Returns the first character in the input queue and removes it.
-\membersection{wxInputStream::InputStreamBuffer}
-
-\func{wxStreamBuffer*}{InputStreamBuffer}{\void}
-
-Returns the stream buffer associated with the input stream.
-
\membersection{wxInputStream::LastRead}
\constfunc{size\_t}{LastRead}{\void}
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}}
+\func{wxInputStream\&}{Read}{\param{wxOutputStream\&}{ stream\_out}}
Reads data from the input queue and stores it in the specified output stream.
The data is read until an error is raised by one of the two streams.
Returns the current stream position.
+\membersection{wxInputStream::Ungetch}\label{wxinputstream_ungetch}
+
+\func{size\_t}{Ungetch}{\param{const char*}{ buffer}, \param{size\_t}{ size}}
+
+This function is only useful in \it{read} mode. It is the manager of the "Write-Back"
+buffer. This buffer acts like a temporary buffer where datas which has to be
+read during the next read IO call are put. This is useful when you get a big
+block of data which you didn't want to read: you can replace them at the top
+of the input queue by this way.
+
+\wxheading{Return value}
+
+Returns the amount of bytes saved in the Write-Back buffer.
+
+\func{bool}{Ungetch}{\param{char }{c}}
+
+This function acts like the previous one except that it takes only one
+character: it is sometimes shorter to use than the generic function.
