class lift_rec_in_channel :This class implements
?start_pos_in:int -> rec_in_channel ->
pos_inand the methods from
compl_in_channelby calling the methods of
rec_in_channel. There is no additional buffering.
The performance of the method
input_line is very bad (consider
to override it, e.g. by
enhanced_input_line as defined below).
pos_in is implemented by counting the number of octets
read by the
start_pos_in: The initial value of the counter for
pos_in. Defaults to 0.
