class lift_rec_in_channel :?start_pos_in:int -> rec_in_channel ->in_obj_channel
This class implements pos_in and the methods from compl_in_channel
by 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).
The method pos_in is implemented by counting the number of octets
read by the input method.
start_pos_in : The initial value of the counter for pos_in.
Defaults to 0.
