-\func{wxStreamBuffer*}{InputStreamBuffer}{\void}
+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.
 
-Returns the stream buffer associated with the input stream.
+Be very careful about this call in connection with calling SeekI() on the same
+stream. Any call to SeekI() will invalidate any previous call to this method
+(otherwise you could SeekI() to one position, "unread" a few bytes there, SeekI()
+to another position and data would be either lost or corrupted).

-Returns the last number of bytes read.
+\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.
