The generic function
stream-read-buffer
is called by stream-fill-buffer to place characters into the region of the buffer
buffer
bounded by
start
and
end
.
stream should be an instance of a subclass of buffered-stream.
stream-read-buffer
should block until some data is available.
result
should be the number of characters actually placed in the buffer (0 if at end of file). This method must be implemented for subclasses of buffered-stream that handle input.
